Navigating shared parenting

[Ifeelreallylow]

So my ex husband is a nasty abusive shit. He verbally mentally sexually and physically abused me for years. Culminated in threatening to kill me when I was divorcing him and since then he has physically hurt our daughter, we went to court for 18 months and they handed him standard EOW contact etc

He still sends me nasty emails constantly blaming me for the fact our daughter is wary of him and doesn't want to do sleepovers (she's 6 and the court said it's not her choice, she's too young to say she doesn't want to)

Anyway, he's asked to borrow swimwear for one the weekends. Saying it might be a one off event and he doesn't want to buy a swimsuit and then having it sitting there unused for a while.
I feel like saying 'no that's parenting. If you want to take them swimming you have to buy swimwear' but then I'll get vitriol back.
I'm going to want favours in the future I assume but of course he'll probably just say no.

I don't know why I'm posting Cos I don't know what I'm asking. I'm just exhausted by all this as I'm quite alone.

:( when he hurt your daughter did you report it it with social services? This is a really tough one. Personally, I'd probably lend him the costume, but it's entirely up to you.

As you've not had much of a response here, I recommend asking mumsnet to move it to relationships. That area of the site has a lot of expertise and are usually very supportive. Just report your post and ask them to move it. Or, dare I say it, aibu? Your question appears to me to be 'AIBU not to lend my ex a swimming costume for my daughter?'

Sorry you're feeling alone.
