Marriage hanging on by a thread. We've not been happy for years now and while I've held on, been desperate to avoid splitting up the family because of the impact on my children (now 16 & 13), it's becoming increasingly clear that the status quo is not to their benefit. DH is now grumpy or detached much of the time and struggling to keep a lid on his resentment. There was a nasty incident in the car last night when he was shouting and swearing at DS, which DD told me about when they got home. This hasn't even been discussed, he hasn't told me about it and I haven't brought it up because he can't cope with any discussion that implies he did something wrong. The fall out from that conversation is not worth it for the atmosphere it would result in. I'm looking for positive experiences of teens coping well with separation as this is my overriding concern. DS has an important exam year coming up and DD could be quite vulnerable to having everything she has known change. I know it wouldn't be easy but I also know I'm pretty resilient. Going for a promotion at work that would make things easier financially too. Main concern is impact on DC. I just keep imagining a situation where they worry about DH and the fact that he's all alone when they're with me. DH isn't close to his family, not happy in his job and doesn't see friends often.
