My DC's dad lives with his mum and she doesn't let the DC go over to the flat. He comes to see them at mine 3x per week. He always leaves rubbish, his mug out, cushions/throws in a mess/on the floor.
I came home from shopping for the day and he's done all this plus unplugged and moved my heated throw and now it's not working! And it's freezing! I have an under-active thyroid so really feel it. I can't say he definitely broke it but just would rather him not touch my stuff. He won't put the remote in the basket it goes but has his own spot for it.
I want to tell him not to come over anymore. But I'm aware this will cause WW3. He might not see the DC which will upset them. I'll also lose financially as he's probably stop giving me money and I'd not get much from CSA as he's unemployed. He has a serious mental illness which means he can't work. He doesn't really do much parenting but the DC love him and he loves them. What should I do?
