Long time user but name changed as this would be very identifying matched with previous posts.
Been separated for 3 years, decree nisi has been granted and decree absolute due in the next few weeks. Ex Husband left me, the standard script and turned out later he'd cheated (I know, what a surprise!) Anyway, none of that really matters as we are far better without his gaslighting, mood swings etc.
About a year and a half ago he started being difficult about maintenance, sorted it out after several months, he dropped it but we negotiated a reasonable amount. Everything returned to normal.
About 6 months ago he got a new much younger girlfriend, moved in almost immediately. Daughter now has to sleep in the front room when she stays with him as she has no bedroom at his new place. He has always had her one week night and one weekend night. Fast forward to start of new term, it's his night to have her the night before she starts (this is always at his mums as he lives too far away to get her to school from his). He tells her the night before she starts secondary school he is no longer going to have her during the week overnight, some bullshit story about her having too many books to carry for two days (they have lockers). Essentially he doesn't want to be away from his girlfriend for a night. Daughter pretends it's all fine but comes home devastated, she's a smart kid and has worked out exactly why he's doing it and feels rejected. I know it's not worth talking to him so speak to his mum and tell her how upset daughter is, she says she'll talk to him but ex refuses to change his mind.
Now he informs me this weekend as he's dropping daughter home in front of her that he's cutting her maintenance in half because he needs a new car. This means we will have to sell my daughters pony as I just can't support it on my wage. Daughter is distraught, I've text him to try and negotiate so that we could still keep pony if I could get a part loaner to help with costs but he won't even acknowledge my texts even though I've been very polite. I can't go through cms as well it's a long story but he's self employed in a very much cash business and fiddles his books so based on what he declares I'd get very little. If I report him to hmrc he will just give up business and go on benefits (whilst working cash in hand on the sly from his home). He literally doesn't give a fuck and daughter has spent the last few evenings crying about how he doesn't care about her anymore, I've tried to reassure her but now I just feel like I'm lying to her.
