To continue with my CMS claim when exp claims it is affecting his mental health?

109 replies

Rainbows41 · 18/09/2025 11:15

I recently put in a claim for CMS to cut all ties with exp. He had previously offered to pay only things related to dc's education and nothing more. I had been told by the DWP years ago that I didn't have to accept that, but at the time I had been on the receiving end of such mental and physical abuse from exp so I was willing to accept anything he offered so as to avoid any further upset.
Years and years later fast forward to now, he has ramped up the abusivrle behaviour again. I have noticed he seems to take pleasure from being asked for money for DC's school shoes/equipment/school travel etc. At times he has attempted to make me feel grabby for asking - by saying he thinks he has paid enough, ie dd's residential trip he paid for but refused to pay for her suitcase and equipment she needed to take with her.

Anyway I am far removed from the nonsense he likes to create and his latest outburst has highlighted just how far I have come in terms of just self growth alone, since leaving him all those years ago. It seems, he hasn't changed his ways and was just good at hiding them. He has started to take things out on my dd. This has crossed a line with me. I will not tolerate it.
IAt the beginning of the summer hols I made a claim to CMS just to cut ties with him altogether. Daughter then doesn't have to ask him for anything and he has no reason to create rows. What's interesting though is that ds doesn't see any of this - because it's not directed at him, only dd. Exp buys him whatever he wants and always offers him opportunities to "earn" pocket money (we're talking £50-£100 a time), whilst DD is left without - no earning opportunity, but she has said nothing.
He is self employed and had recently been blosting how much he was earning whilst still being nasty towards DD. He has been very abusive towards her and her friendships (something he used to do to isolate me). She snapped and told him he was out of order. I decided for her sake (and mine secretly), that a CMS claim would give him one less thing to control and abuse.

CMS have come back and said dc's are entitled to zero. Apparently he is relying on universal credit and has swindled his earnings to make it look like he is earning the bare minimum. I was fully expecting him to hide his earnings, and it hasn't surprised me he has done this.
I am financially in a position to cover anything my children need and want, so not relying on him to cover educational bits is no problem for me. At the end of the summer hols I would have usually asked him for money to pay for DC's school travel passes along with some uniform and stationary bits. I have covered these now myself.
The day after I was informed by CMS of the zero entitlement, exp contacted DC's individually and told them to each pass on a message to me : "this is the last time and I mean it, I am offering mum one last chance to accept my offer of going back to the former agreement". I listened to my DC's telling me this and I didn't respond whether I would accept or not (I was in shock if truth be told at the sheer audacity of exp).
DD asked dad directly whether he would pay mum the bus pass money, and he told her no and said, I quote "this is what happens when mum messes with fire - she gets burned!". I couldn't believe it when she told me that. He said he would only pay anything they needed from this point forward and will not reimburse anything I had already covered. He also requested that I cancel the CMS claim and only then he would think about paying their costs, yet unsurprisingly he has purchased equipment for ds he needs for college whilst dangling this CMS claim over daughters head as leverage.
However, he is still harassing dd about it and has ramped up the abuse. He is threatening to kill himself over it. He has told her that hers and my actions have caused his mental health to decline rapidly.
I had previously blocked him, since the beginning of the summer hols. However, due to the abuse towards DD I have had to resume contact and tell him to back off! I have asked him why he is so upset over it all when CMS aren't even taking a penny from him. He won't say, but I think he doesn't want the trouble of having to continuously hide his earnings from the government. That's not my problem. That's his.
I had told him last night that if he carries on with his coercive behaviour towards DD then I will get the police and ss involved and they will look closely at his mental health to decide whether he is actually fit to be around my DC's. When son came home last night, after his suicidal threats, he had no idea of anything being untoward. I casually asked him if he has spoken to dad today, he said yes. I asked how he seemed. Son said he was absolutely fine and asked me why. I knew he was just ramping up for my daughter and playing a callous act. Do this is why I added in my message that the police and ss will look into his mental health, so as to call him out on his bullshit
After my message was sent, he started taking it out on DD and messaging her about it! He was asking her what he should do, he feels so mentally unstable and it's all mums fault.
I cannot believe he did this and I am at my wits end. I haven't messaged him since. I've said what I needed to and I absolutely mean what I said. I don't do 'he said/she said"
' nonsense, nor do I take part in any kind of tit for tat.
Daughter is becoming very confused and worn down by it all and has asked me to cancel the CMS claim as she wants all this to stop. She says she doesn't know whether to be on dad's side or mine and is confused as he keeps saying stuff about me. I have calmly explained to her there are no sides to take. I explained that people can easily say things but their actions will always reveal the truth. I told her she can make up her own mind about dad and I will never judge her or love her any less. I have advised her that she would benefit from some counselling sessions away from me and dad, so that she can let off some steam and get unbiased advice.
I have explained that her dad seems to be going through some kind of mental decline and that he shouldn't be taking it out on her.
I was very careful not to give her too much advice as she was in information overload. But at the same time I didn't want her to be left with all those negative thoughts whirling around her mind festering. She was upset that I had messaged dad and had gotten involved. She demanded to read my message, so I showed her. None of it was nasty. No name calling or insulting text, just facts.
She looked at ease after reading it and actually told me she thought it was a good message (teenagers?!).
As I said I've blocked him again. I told her it would be better if she gives him some space and avoid him for the time being so he can calm down and work out what's going on his head. She also needs to decompress.
She said she was worried he was going to use her giving him space against her for when she does eventually go and see him.
I advised her to put his messages into the archive folder, so that she can look at them along with any new messages when she is in a better place, if she so chooses to.

I don't know what to do now. I don't want to close down the claim. I shouldn't have to. He is making out that I am being unfair and causing issues. I'm literally doing the right thing by cutting him off from me, and removing his "power".

I did say to him in my message that when he asked the kids to tell me about his "last offer", they also told me he wanted me to set up a bank account for DD (son already has one), so that he can pay money into that for educational bits, rather than paying me directly. I have since, set this account up for DD and when telling him about it in my message, he relied saying he would prefer to set up his own account and pay money into that instead. I know exactly why he has said that. It's to avoid paying my daughter anything at all and still keep control of anything he intends to put aside for her and use that as leverage in fiture. It's all controlling bollox.
I'm taking her out on the weekend to buy her the bits she needs. I've advised her not to ask him for another thing.

Keep the CMS claim open, force him to either pay or to have to keep lying.

Causing this much drama and trauma to your DCs to try and get out of paying for them is just 🤢

Ignore him, keep being there for your DCs as you have been and let him make whatever decisions he makes without rising to him.

imtoooldforthisshite · 18/09/2025 11:31

I would imagine the CMS looking into his ‘zero’ earnings has spooked him that he’s in the spotlight for hiding his money.

imtoooldforthisshite · 18/09/2025 11:33

Sorry in case I wasn’t clear…carry on with the claim.

Rainbows41 · 18/09/2025 11:33

I've just edited my post to correct several typos.

And he's probably thinking about his next tax return or meeting with his accountant and wondering how he can tally claiming universal credit with his earnings and when exactly HMRC are going to come knocking, which is leaving him squirming.

bombastix · 18/09/2025 11:38

I don’t have advice but I wanted to say what a despicable man he is. Suicide threats are just the mark of the lowest of the low. If you took him to court on access he would have explain why he wasn’t an abusive bastard to your children. The possibility he’s done similar to your DD would be very serious.

Keep on with your claim. His efforts to involve his children is disgusting.

Rainbows41 · 18/09/2025 11:39

Thank you for your reaponses.
I was dreading being told that I was being unreasonable and to drop the claim. But if truth be told, I'll be damned if I'm going to let him control me by bowing down to his unreasonable demands, even if it means I get zero for the kids. I fully expected to not get much or anything at all, anyway. It's clear he is throwing his toys out of the pram at having his "power" ties cut.
I have told him I will continue paying for anything they need and he can pay into their accounts anything he wants to. But he is refusing to do it for DD.

Saying that he has emotional problems due to you asking for money to support your children, to your children is scummy and emotionally abusive

Ponoka7 · 18/09/2025 11:47

What's his housing position? It's all well and good hiding income, until you need to rehouse/upsize/BTL etc, as one posters ex found out. Now with everything being linked, it impacts credit. He will know this, keep the claim open, but speak to your son, surely he sees the favouritism? He will then have to justify why he gives nothing to your DD. Your DD doesn't have to keep seeing him.

CrackingOn50 · 18/09/2025 11:50

I'd be calling the emergency services if he was threatening suicide. I also would be supporting your DD not to see him and reduce her exposure to his horrible behaviour.

He's a cunt. He's emotionally abusing and coercing your children, especially your DD.

What sort of scum would blackmail their own child with suicide? I'd also be worried about DD being vulnerable to abusive relationships in the future as it's being modelled so well by her father.

Well done for escaping him, he's lost the power to control you so he's doing it to the DC.

Yes. He is absolutely the scum of the earth for doing this to her. And I have no doubt the courts would look at that behaviour and ask him what he was playing at! I'm sure they would demand he take parenting classes, and seek self help and advise to not see the kids until he is in a better place. This would be never imo! It's just scary how similar his actions are to when we were together.
It is very draining. He can be relentless and will drain any life out of anyone. He is a cunning liar and will easily try and manipulate anyone and any situation to suit him.
Looking back at some of the things he has done to DD is just heartbreaking, for instance he will buy ds a mob phone on contract and will give him upgrades periodically. But daughter will only be given a phone and any upgrade as a birthday or Christmas gift and that's her lot! It's horrible how he treats her but she hasn't seen it luckily. It's just nasty. I'm just remembering actually before I cut him off at the beginning of the summer hols, he told me as I had chosen to go down the CMS route, that I can now take over the kids phone contracts and asked me to pay his girlfriend money to cover the remainder of their contracts?? The sheer brazenness of it!!. I reminded him that they were gifts from him. I told him if he didn't want to pay for their monthly contracts though, that I would be more than happy to get them changed over when their current contracts end! he hasn't mentioned it since. CF!

What is the background to him favouring his son over his daughter? It’s disgusting.

See this fills me with so much dread - the bit about him modelling how her future partners should be. It absolutely makes me sick to the stomach and was the sole reason for escaping him all those years ago - so that my son didn't grow up just like him and so that my daughter didn't end up with a partner the mirror image of him.
I do have an older son from a former relationship and he is an adult. He is every bit the gentleman. How he speaks and acts, he is the perfect male role model for my younger children. They absolutely adore him and look up to him in awe. They think he is so cool and all their friends love him. He is naturally very handsome and has such a calming aura about him. I am so proud of all of my children, and I work so very hard to ensure they are well rounded. I just pray and hope that she doesn't end up wanting to be with anyone who treats her any less than what she deserves.

I was always advised if someone is threatening suicide, to call 999 and send police/ambulance (not sure what is sent).

If it's a real threat, then they get the support they need. If not, then they may be reluctant to make these kinds of empty threats again just to try and control you.

I would not drop the claim.

What age are your DC? (Apologies if missed). Does your DS see the discrepancy between the way he and his sister are treated?

I know this is the only way to get it all to stop. But she can be stubborn so I can only gently advise and allow her to make her own mind up. .The DC's are teenagers, so they absolutely don't have to see him if they don't want to.

The idea is to upset you as I am sure you have twigged. It’s also pretty clear he regards your DD as a proxy for you and emotional abuse about suicide to children is taken seriously by courts.

Honestly his clear intent is to divide your home and your children against you. What a bitter nasty man he is. I am guessing he is thoroughly obsessive and did not get over being left by you.

ElectoralControversy · 18/09/2025 12:04

So he's not just avoiding tax he's fiddling benefits too? Lovely. No wonder he's panicking.

I think HMRC can do an investigation where lifestyle is out of whack with declared income but I suppose there's no point poking the cobra here.

gamerchick · 18/09/2025 12:05

You do know what to do. You keep the claim open and follow through on whatever you said to him to make him stop.

Keep all the messages he's sending to daughter.

I said to daughter last night that we should call the police if he is making those suicidal threats. That's when son came home and I asked him when he had last spoken to dad and asked how dad seemed when he spoke to him. He said he was absolutely fine and not a bother on him. So I decided not to bother the emergency services with him. However, if he does it again, I will make that call because when they turn up he will be so embarrassed that hopefully it will shut his false claims down!

Ilovepastafortea · 18/09/2025 12:05

Your children need a roof over their heads, gas, electricity, TV licence, food etc not just stuff for school. This is why you need proper maintenance not 'hand outs' for things that your ex feels are necessary. He's using this as a way to continue his abuse and I would definitely continue to CMS claim.

I understand that DWP are in the process of employing hundreds of new Fraud Officers to examine UC claimant's bank accounts (yes they can get access) and examine the books of those who are reporting self employed income comparing the figures with HMRC declarations. Your ex may well come unstuck once they get to his claim. Karma indeed.

DuckbilledSplatterPuff · 18/09/2025 12:06

Do your son and DD visit him separately? or together. Surely DS must have noticed some of this crap. I think if he's causing DD so much grief - does she have to see so much of him? and can she only see him when DS is there. Will DS stand up for her?

gamerchick · 18/09/2025 12:08

Yeah always ask for a welfare check when someone threatens suicide. It usually nips shit in the bud if they're full of it.
