I'm sure I'm not being unreasonable but actually starting to doubt myself after two and a half years of gaslighting, emotional abuse and coercive control 
Stbxh has my dc from 3pm Friday - 3pm Sunday. Friday night I received 36 text messages and various missed calls. Mainly calling me names because I'd arranged to take my kids out when I picked them up at 3 on Saturday. I ignored him as much as possible. 6:45am Saturday he text me and told me to come and collect them as soon as they woke up (which was before 8am!). As he wanted to be alone. I did collect them.
I later sent a text saying it was unreasonable and I was concerned about his mental health and maybe a time period without having dc for sleepovers might benefit him. He agreed.
However my AIBU is this! He later text saying he had been up all night while my dc were there thinking about killing himself. I now don't want my children going for sleepover at all ever and also want any contact supervised by his parents. Is that unreasonable? Sorry it's so long!
