I think the reason he wants to separate is because of his depression but he thinks we just aren’t compatible (20 year marriage), but I think if he finally tried to sort his depression it might be salvageable. He wants to carry on living together to coparent but be separated but I’ve said a prerequisite for that is still that he has to fix his depression. He takes medication, had counselling a year ago but over last 5 years drinks alcohol fairly heavily a few days a week, no exercise, overeats and doesn’t prioritise sleep, very stressed with work, doesn’t prioritise parenting. 6 months ago he said he never wants to have sex again but before that said he was happy to try and improve our sex life. I don’t mind people occasionally binge drinking but when he does it it just rubs salt in the wound that this is why he hasn’t fixed his depression/a symptom of depression and his depression is why I’m facing divorce and my kids are too. I’m not sure I can live around this. Thinking that I need to be brave and go for proper separation not cohabitating even if it takes a while to sort out. Not sure how to deal with my anger and frustration at him for messing up all our lives while he doesn’t take responsibility for his depression, while living together.
