Our issues have been building for a long time.
Together 9yrs and married for 5yrs. I have a 16yo DD.
He cannot cope with a teenager behaving like a teenager. Eg, pushing the boundaries, eye rolling, slamming doors, making bad choices etc. I can't say I'm thrilled about it either however I try my best to keep her on the right path. She's had 2 years of counselling and has also recently been diagnosed with bulimia.
If they got in to an argument then they'd both come to me moaning about the other one, expecting me to take their side. I was constantly put in a situation where no matter what my opinion I'd end up pissing someone off. My anxiety grew and grew and I'd end up a mess at the slightest sniff of tension between them.
If I didn't take his side and "punish" her in the way he saw fit then he'd basically call me a bad mum.
He absolutely hated her dad and had so much resentment towards him festering inside him, and I genuinely think he viewed her as an extension of him as opposed to her own person.
I asked him to go for counselling but he has refused...said if he needs to go for counselling because of his family then he shouldn't be in gay family any more.
Christmas was the final straw for me. He refused to join DD and I on our usual Xmas Eve traditions. He didn't get either of us a Xmas gift, didn't open his gifts from us (still unopened), didn't join us at my sisters for Xmas dinner. I had massive doubts for a while but that was the last straw for me.
I have been sleeping in the spare room since Xmas and I'm in the final stages of securing a rental property for DD and I.
I'm definitely no angel and I'm not perfect and have many faults, but I admit to them while he can't admit to his or accept he needs help. I lost all respect for him when he screamed that DD and I were a pair of arseholes.
