DB seems happier too, and it's good that we're on the same page about her. He got a lot of shit from her over the years, being the scapegoat and I think he feels more now that it was never him, she's just mad. We're closer now too I think, we were always close but we talk more now as I can skype him and talk freely cos she's not around.
DH is happier. He'd started smoking again through stress while we were living there but hasn't since before we moved out. He's still out of work, but does all the cooking, cleaning and childcare (including a lie in for me at weekends :)). I mostly do the laundry, but I like laundry...I find it calming, weirdo that I am.
DM of course would never admit that she was happier or had a better life now, but she does. At the weekend I went to a Medieval Xmas market with her and the kids (had been with DH the day before). Beautiful sunshine, lovely place. We walked round for about an hour and a half and had a coffee. Great morning, no complaints about walking or pain or anything. Then, yesterday DD has her xmas nativity. DM came and watched from the back (only 2 seats per child) and stood for about an hour, saw DD after and said she'd enjoyed it. She shops, cooks, cleans, does her laundry by herself, gets to eat what she wants instead of complaining about what we cook.
We have the occasional blow up or attempts at drama llama behaviour, but things are so so so much better. I still feel guilty about stuff and have to be careful to keep boundaries up and not be too much of a people pleaser, but I'm getting there.
