Not quite sure what to do.
Have just separated from DH of 20 years. It was my decision, and a big part of it was due to DH's mental health over the years. He always been up and down, very anxious and depressed, and the last few years he had a mental breakdown, left his job and spent all day all home just on the sofa playing his xbox. He has been on antidepressants for years, and seen many counsellors and even a psychiatrist. The last few years at home he was disengaged with me and the dc, was angry, irritable and cold. My ds (now aged 16) sobbed to me a few times about how DH was, and how he thought he was narcissistic and didn't ever do anything unless it was for himself. My ds actually said to me "Why did he have a family and get a house and garden if he just wanted to do his own things all the time?"
Now we have separated my DH seems less stressed (he's in a rental place so no responsibility, and sees the dc at weekends). I feel he is in the role of a "friend" to the dc, he likes going on walks with them or watching TV with them.
But I'm worried about ds15. He initially seemed ok when we separated but now seems angry and spends most of the day in his room. He has GCSEs coming up and has done no revision and says he doesn't want to go to sixth form. He is bright (was predicted 7-9s) and I feel heartbroken he's throwing it all away. He is now saying he can't wait to move out of home, even though I try to make it a calm, fun environment with me and dd13. I know dads are important at every age but I'm thinking especially at this age, the son probably looks to the dad as a role model. And I know DH is not the worst, but how he has been was very difficult for us, and now he just spends the day pottering around on his own, no job, no direction or focus, basically living like a single guy in his twenties- surely that must be having an effect on ds?
When DH and I told the dc we were separating we kept it very simple and just said that we wanted to live in different ways but were still friends, and our priority would always be the children etc.
I'm just wondering if I should talk to DS about DH's mental health struggles. I've never told him about it as i didn't think it was appropriate for him to know. But I'm now thinking that might help him to make sense of the situation otherwise it's probably very confusing to him why DH is like this. Or would knowing about DH's mental health add to ds's problems? Any advice welcome!
