I've been with my DP for 3 years now, and for almost all that time his parents have treated me so badly. Everything I do is wrong, rude, mean, controlling of DP etc, even if we make informed decisions as a couple like where to book our holiday or how we want to decorate our home they accuse me of steering him toward my choice. I don't btw! DP and I work as equals. The rest of his family love me to bits and I love them but I'm never welcome to visit family if they are there so DP and I go round to see everyone on our own and it must look awfully strange that I'm not part of their family unit and I can see them making out that I didn't WANT to be there with them to try make me look bad.
I've come to realise its mostly FILs doing, my MIL is relatively nice to me on her own, and I find it confusing how she switches off and goes cold when he comes home from work and I'm visiting, or if he is anywhere with us. I've come to see she does it for show because he hates me so much, she lets me know in subtle ways she knows I'm not all bad but wont stand up to him and have peace in the house? 
DP and I think shes scared of him. He's quite domineering, very narcissistic, he's rude, selfish and will spoil your day if he's had a bad one so nobody can be happy unless he is. He treats her like a live in maid, he's forever doing gross things like leaving bits of food lying around to decompose and then goes mad if the house is a mess and she hasn't cleaned it all up after him, he sulks if his dinner isn't on the table after he walks in from work and he is only affectionate toward her when he wants something or if he's being so godawful he needs to make up to her to be sure she doesnt walk out on him. She was talking to him the other day, stopped mid sentence because she realised he was ignoring her and he didn't even notice. Wtf?! 
DP and SIL are both a bit emotionally scarred by him, both have horrible self esteem issues, cant express their emotions and both feel inadequate because he's always made it clear they aren't good enough. SIL never can be cos shes a girl and he never wanted one, and DP because he wont let his dad live vicariously through him and finally begun to take his own path in life when he met me and finally got a bit of confidence, not being big headed here, DP tells me so, but its another thing FIL hates me for.
AIBU to want to somewhat cut ties with him? I'm sick of feeling on edge and definitely don't want to in my own home. DP doesn't want him around either but feels obliged because he feels sorry for MIL and she wont go without him. I sort of think it's her own fault for putting up with it, I'd have LTB a long time ago. I would be happy for DP to see the both of them of his own accord, I just don't want them in my home or to have our DC unsupervised when we have them since he's emotionally abused his own kids and MIL never stopped him. The whole family is involved in a sport and if one of our future DC wanted to play and not the other I can see him favouring DC1 and ignoring DC2 for not being good enough. If my DP wanted to take the kids to see them for supervised visits I wouldn't mind, but I wouldn't go because I feel judged and don't want them to tell me what a horrible parent I am and belittle me. I wouldn't even mind meeting MIL for coffee and a chat, but not him. I have tried to be lovely to him, I always do xmas and birthday cards and little gifts, I come help clean the house and make the dinner and I'm a saint for it considering the circumstances but I'm ready to give up because he just hurts me again and again. AIBU, and for the record, should she LTB or is it just me? of course i dont want their family to be broken, but its become a dictatorship instead of a family anyway...
