To lose it at my ex for not sticking to shared calendar.

I’ve been co-parenting with my ex for over five years (although “co-parenting” feels like a generous description). I do about 90% of everything: childcare, school admin, appointments, activities, birthday parties, forms, uniforms, the mental load…you name it. He pays a token amount of CMS that hasn’t increased in five years, so I’m now going through CMS properly to make sure I’m receiving what I’m actually entitled to.
We have a shared calendar, but it only seems to work one way. If he puts that he’s busy, I have to accept he won’t be seeing our daughter that weekend. If I book something in weeks or months in advance, it somehow doesn’t count. He’ll make plans anyway and then tell me I should have checked with him first.
It’s become noticeably worse since he started seeing someone about nine months ago. He’ll agree to have our daughter and then, a few days later, suddenly can’t anymore. I strongly suspect that’s after speaking to his girlfriend. It’s incredibly frustrating, but more importantly it affects our daughter, who deserves consistency.
He seems to expect me to be the default parent, do all the day-to-day parenting, and then fit around whatever suits him. Today was the final straw. I’d booked next weekend out over a month ago because I need to work, and he announced he couldn’t do it after all.
I completely lost my temper. Five years of resentment came pouring out.
Did he take any responsibility? No.
Did he apologise? No.
Did he offer to change his own plans? No.
Instead, the expectation was that I’d rearrange my life yet again.
Part of me feels guilty for losing it, but another part of me thinks it was inevitable after years of this.
Am I being unreasonable to expect a father to honour the time he’s agreed to have his child, rather than treating it as optional? And for those who’ve dated or remarried, is it unreasonable to expect a new partner to understand that children come first and that parenting commitments aren’t something you cancel because you’d rather spend the weekend together? I can’t deal with the chaos anymore!

@nomasalready got the text about Christmas this week! Hilarious he misses first day of school, Father’s Day, doesn’t take her on holiday but Christmas he must have her!

He can go swing. What's he going to do, take you to court? No way!

He just wants the nice bits.

I’m not blaming her, I said I feel sorry for the poor child.

Your posts are very unhelpful and not necessary.

That poor poor child having two squabbling parents 😥

Don’t you mean that poor poor child with a useless piece of shit for a father

bluebirdsandblueskies · 08/07/2026 21:50

@BinNightTonightwhat an absolute selfish prick! And again another woman who were not allowed to blame, but fuck just stay away from married men!

It's not clever or kind to blame a woman who does the bulk of care for her child when the useless culprit is her ex.

YANBU. Could you set up a firmer schedule re contact? How often does he actually see your daughter?

My ex walked away when our child was 11 months (completely out of the blue), he visited him 4 times over the following 4 months, then disappeared 6 months ago and i haven't heard from him since. He was cheating on me with a girl in work, she knew he had a baby as he brought him to work a few times (with me), it was very common knowledge that he had a partner and a baby. I wonder what she thinks, how she can trust a man who can abandon his child (and partner) I dont blame her, if it wasnt her, it'd be someone else, but how could she get with him knowing he had a family and stay with him, knowing he hasnt seen/asked after his baby for 6 months and counting. I find it baffling. Of course hes to blame and he'll be telling her lies, but she will know deep down that hes moved to her, 5 hours away from his baby, and he doesnt see him. Insane.

@NeatPinkFinchthank you! My sentiments exactly! But he is the the bigger twat in the picture! Interestingly uploaded all the text conversations to chat got as I feel I’m going mad sometimes. Love the pschyo analysis of it all and really flags up with a narccistic, conflict driven shit he is! DARVO kept coming up again and again for all his responses. Given me a lot of power really!

Don't blame gf you don't personally know. A rubbish dad before and a rubbish dad after doesn't make it her fault he is even worse. I found after a year of making arrangements him not sticking etc that I was fed up and if he was bothered about kid he would contact me and yep that was 15 years ago

Actually I do blame women who go anywhere near shit fathers. Get some standards.

It doesn’t sound like you have a fixed schedule. I’d put that in place first. It’s better for DD anyway.

Then don’t accept changes. Sort out childcare if you need it during your time and expect him to do the same Ditch the shared calendar as you won’t need it.

He probably won’t even stick to that but that leaves you in a better position that you are in now because you don’t have the chaos and mental load of organising a week by week schedule.

Mu expectation is that he won’t be part of DDs life at all in a few years. So focus on a set up where you have built your own village and can cope with that. Don’t waste any more time on trying to get this feckless man to be a proper parent. He won’t ever be. Your job is to deal with the fallout from that.

@NoCommentingFromNowOnoh I wish I could! But I wouldn’t do that to my daughter. Funny he was away on Father’s Day and didn’t make her first day at school but will come banging down the door to have her on Christmas Day!

I would not let him have her at Christmas at all.

@TheDevilWearsi am so sorry you’ve been through all this. I feel my situation might not be quite as bad as that but I’m glad you had the courage to do what you needed to. It is ALL about control. His logical arguments don’t make sense and at the weekend after agreeing to take DD to an event that had been planned and paid for - he just didn’t show up (as one of the other mothers text me to ask where DD was) there was no reason just the fact I’d text him the details and he replied I wasn’t to dictate what he did with HIS time (he had agreed to it last week)! I was livid and text him how selfish he was and how I felt sorry for DD. Cool as a cucumber he replied ‘this abuse has to stop. I am keeping all the screenshots and I won’t be afraid to use them.’ The mind boggles - when he pays £12 a day for his daughter and essentially has her for a one kr two nights a week maximum! I think he’s made me feel so confused and anxious all the time I have no grasp on what is right and what is wrong! He has really got into my head thinking I really must be the problem!

Sadly I was in a very similar situation when my children were younger. Tried mediation - he didn’t show up. He refused to agree to a regular schedule or a parenting plan. Continually flaked on arrangements at the last minute and only spent time with our DDs if it suited him. I was responsible for everything. The mediator said to me that you cannot force someone to be a parent. And as much as that stung, she was right. I left the country with my DDs. He accused me of trafficking, took me to court claiming alienation, sought sole custody … it’s not about your DD it’s about control and post separation abuse. My ex lost his claim for sole custody 🙄 and chose not to see our DDs for eight years as dealing with me was damaging to his mental health 😂

Dear me, you seem to have made more posts about her than him even though you claim that you "blame him 100%".

bluebirdsandblueskies · 03/07/2026 14:39

@PinkipaI totally accept everything you have said about him and I’m more than aware the bullshit he’s probably told her about me! How awful I am etc etc! But I also think any woman who is married for twenty years, has two grown up kids and wants to date someone who has nothing to their name and a five year old kid is a woman scared to be alone and needy! She isn’t to blame for his behaviour but she isn’t helping it either! His behaviour only got worse when he started dating her 10 months ago - however he is the father and should be better! And it’s 100% his fault. But needy women need to sometimes open their eyes! Surely you can’t be that naive/stupid (needy insecure women can be as you see it all the time)

I blame him 100% but I also think she is complicit. Just because she is a woman it doesn’t mean she can’t take accountability or hold someone to account. If she wasn’t complicit she wouldn’t be with him

I wouldn’t give her a nano second thought in this.

firstly he will have blown a load of smoke up her ass re the situation
secondly, ultimately this is all on your pathetic ex if he is so easily swayed by a new partner saying she’d like more time with him
and thirdly, doesn’t occur to you he’s telling you this about her but actually - he’s using her as a made up excuse because he wants to limit his responsibility?

I mean he’s been paying you peanuts even before having met her . Hardly father of the year.

And who knows what crap he’s told this girlfriend in any event ie he’s desperate to have more time with his dd but you make it so hard.

Exactly, he probably told her a pack of lies, that you won't let him have dd, poor him, or maybe never mentioned to her that he was supposed to. It's his fault 1000% and nothing to do with her. A woman can't make a man spend time with his kids, as you are also finding out.

Pinkipa · 03/07/2026 14:19

bluebirdsandblueskies · 02/07/2026 16:07

@ToThePoint2026he is shit but I also find a desperate pick me girl can be an enabler too! I’ve never met her and neither has my daughter but imagining not questioning why your man doesn’t spend more time with his daughter!

I blame it squarely on the father.

Op if you got a new partner and he started suggesting you saw your children too much…. Your reaction would be horror and immediate dumping.

Not so with this man.

And who knows what crap he’s told this girlfriend in any event ie he’s desperate to have more time with his dd but you make it so hard. And probably tells her he pays way in excess of cms!

Esmeraldathe3rd · 02/07/2026 15:16

You need a set schedule that both of you stick to. No switching or anything. If something comes up on your week you plan alternative childcare.
Go to mediation. If that doesn't work you go to court. It's not that expensive if you self represent which really isn't that hard.

I for one am certainly pleased that no court will force a parent to have care of their child.

Not only awful for the child, potentially dangerous and completely unworkable
