Bio mum makes my blood boil

81 replies

How do you cope with an entitled leech of a bio mum? This woman plays the victim in every possible situation and is sucking my husband dry financially. She refuses to acknowledge my existence, but assumes I will happily provide childcare for her. Oh and she loves to speak badly of me and my DS in front of SC.

My hate for her is all consuming. Is it bad that I wish her a terrible life?

I honestly don’t think I can live the rest of my life like this. What do I do? How do you cope?

How long have you been together?
How many children does he have?
How many children do you have?
Do you have any shared children?

We are working on it as we speak!

She has manipulated him to think that he is a bad father and so has walked all over him. Pays CMS plus mortgage. She also demands that one of her children be at club on his days while I stay at home with his other child, which I’ve now said will not happen anymore.

CMS plus mortgage?? Why??? Does he not have a backbone??

A bio mum is the actual mum. End of. Whether you like her or not.

Thank goodness you popped by to say this. No one had mentioned it till now.

OnlyMabelInTheBuilding · 21/11/2025 22:43

Just stop the childcare. Ignore her back.

Zen life.

If he continues to pay the mortgage voluntarily when he doesn’t need to, tell him you’re off. And that he can pay your new mortgage too.

Honestly, not many men are worth the pure hell that exes and DSC often bring. He needs to support you as much as her, but sounds like this will only start if you stand up for yourself.

depends on the length of marriage and the terms of the divorce settlement indeed mortgage payment might be reasonable especially if the plan is to sell once the kids 18=21 ish.
same with sports clubs if well established.

Unless hes a ridiculously high earner this doesnt happen. The mortgage is solely taken over by the resident parent and they have to prove in court their affordability. Yes the NRP can agree to continue paying a contribution but as the DH in this situation has married I highly doubt that is in place.

KnickerlessParsons · 21/11/2025 22:57

Perhaps she hates you because you keep referring to her as “bio mum”.

why did you leech onto a man who is unable to set sensible boundaries?
why did you have a child with him who is unable to establish child care of his existing child on his own?

I am actually the opposite of a leech, thank you very much. I am a high earner and provide for my own son AND step children. I pay half of all our expenses. The only reason we live in a nice home and each SC has their own room is because I can pay half.

He has been manipulated by this woman for many years to feel like he is a terrible father and legally obligated to do these things for her. She tried to manipulate his family against him. It’s only been until recently (with the help of a therapist) that he’s come around to the fact that this woman earns enough money to support herself and she actually doesn’t need his support.

He’s not helpless op. Your anger is misdirected.

CinnamonBuns67 · 21/11/2025 23:23

Honestly ignore her back. I get it but it's not worth your peace and you give her too much power, been there done that. Don't do childcare. Don't do anything for her. Your partner only needs to take care of his responsibilities to his children and thats it. She tries to control your household? Ignore her and carry on as you intend

Quiltedconcrete · 21/11/2025 19:54

Maybe stop referring to her as ‘bio mum’?
that might help.

she is the kid’s mother and it’s a pretty disrespectful way to talk about someone.

You’ve said she is ignoring you, so how can she be doing that yet expecting you to provide childcare?

the missing link here is your DP. I’m guessing he’s the one she is expecting to ‘babysit’ the kids but he’s passing it on to you.

She refuses to give him 50/50 contact arrangements because she wants the CMS. What kind of mother does that?

Perhaps he wants to ensure a secure home for his children? Some men do.

Birdie100 · 21/11/2025 23:46

He still wants to provide for his first family.

ohdearmemummy · 21/11/2025 20:19

I’m in your boat, my step children’s mum, is awful.

She had the affair. She left. But she is hell bent on controlling my husband. She hates him more than she cares about her children’s mental health. It’s really sad.

your options are to leave.

or to take back control by not making it your issue to carry. Let him take responsibility (or not) and you focus on your family. That doesn’t mean neglecting your step children. You can be all present but shut any noise that hurts you.

Solidarity my friend ❤️

thanks for being the only person on this thread to actually share something helpful

Well you lost any credibility by using the term “bio mum”

If you don’t want to have to deal with an ex in your life don’t get together with a man with children. Pretty simple. As others have said would love to hear her side as doesn’t sound as clear cut as you are making out

Tiswa · 21/11/2025 23:50

you do get what CMS is don’t you him paying for his children? Not supporting her because I feel you should.

also you don’t have to be with his child when the other is at a club but if you mean she wants her oldest to do a club he likes?

and some recognise that 50/50 is for parents not children and doesn’t work for all

I assume the house will be sold though? And if it hasn’t why not

Bellyblueboy · 21/11/2025 23:53

Rtmhwales · 21/11/2025 19:59

I don’t think it’s necessarily meant to be disrespectful. Virtually all other forums other than Mumsnet use bio mum (BM) to distinguish who’s being talked about. They also distinguish their own children as bio children (from a previous relationship) or ours children (OC/OD/OS) to distinguish shared children. It just comes across on this site as inflammatory but it rarely the intent.

In any circle I am in the term bio bum is the same as birth parent. A biological
parent who surrendered their rights - it is used to distinguish between ‘real’ adoptive parents who do all the parenting and biological parents who only have a biological link. I know adult children who have decided it’s time to meet their biological parents. I have never hear someone in real life use this to refer to the actual parents.

I think it is intended to be disrespectful I this usage.

If he wanted 50/50 and he took it to court- he’d get it. It’s pretty much considered the starting point if it went to a court. Even really crappy fathers get 50/50 if they push for it.

Ophy83 · 21/11/2025 23:58

CMS is usually so minimal that it isn't unreasonable that he should pay for the housing of his children if he can afford to do so, which is sounds like he can as he is also managing to pay half of your joint living costs.

If he wants 50:50 he can ask the court to order that, or he can tell her that it is a step he is willing to take and invite her to agree.

The kids shouldn't have to stop clubs just because they are at yours, but she can't dictate how that should happen- it's up to the 2 of you how to juggle that, whether your dh takes both kids with him or if you are happy to have one at home. If the child is old enough that they require minimal supervision it would be pretty harsh for you to insist on them going out if you're going to be home anyway (if you're not going to be home then it's on your dh to figure things out).

Hopefully the therapy will help him to regain control of his life and be able to interact with her, without being a pushover and letting her control him.

BreakingBroken · 22/11/2025 00:35

certainly some of these qualities in your dh (being manipulated, overly generous with is ex, low self esteem) were present prior to you having a child with him.
what made you marry him knowing full well the situation at hand?
