Name changed for this.
Back story - I own my house and live with my DC. EXH only sees DC at my house due to their physical disabilities. He could have them for
the day at his house but refuses. They can't stay overnight with EXH due to their needs. He comes up to put DC to bed but will not come in the house if DP is there. I used to ask DP to go out for a walk or go for a pint when EXH wanted to put DC to bed but stopped doing that as it seemed unfair to DP. So every time my DP is here on an evening that EXH wants to put DC to bed I text him to let him know DP is at the house and he always refuses to come up. I don't stop him, he just refuses to enter the house as he does not think he will be able to 'control himself' if he sees DP!!! (His words, not mine) BUT, DP will be moving in shortly and I know that is going to cause issues with EXH. He hates DP, even though he's never met him, and I am scared of him. He's never been physical with me but has threatened to kill me previously when we were arguing. (logged with police and have an incident number).
So now I don't know what to do. Part of me wants to ask DP to sit upstairs in case EXH still wants to come up in the evening. DP doesn't really want to do it but will go along with what I want. I'm not even sure that EXH will come in the house but that means he won't see his DC. But part of me thinks, Fuck it! That's your problem sunshine, deal with it. So, AIBU to ask DP to sit upstairs in case EXH wants to put DC to bed???
