I'm not disagreeing with everyone who says he's taking the piss etc but having been in the exact same situation, I also saw where my DH was coming from (in hindsight after counselling).
He was under pressure to pay the mortgage (or at least he saw it that way). And he felt that if he stepped off the career gas even for a second, he'd lose out and in some way put us all at risk. But putting us financially at risk was only half of it. Putting his own career and all he'd achieved was the other half. He loved his job and didn't want to jeapardise t.
In addition, my DH went to the gym all the time and I could see why - he worked bloody hard and had a long commute and needed some downtime. i could see why he'd want that.
But what he wasn't seeing is what I wanted and needed. i.e. companionship, support, some time out too, the feeling that I wasn't in this parenting lark alone. And what I felt was that he got to put himself first while I never had that priviledge. What builds up is mega, mega resentment. And the only way to clear it is to discuss it. But when you have a man who is too busy/tired/attached to his blackberry to talk, it doesn't work and your communication translates as nagging, which makes him even more keen to spend time away from home.
after reading your post today I asked my husband what his trigger was - what made him realise that things had to change, because god knows I'd been trying to change things for years. He said it was multiple reasons:
- he'd got to a point in his career where he felt more secure and felt he could ask to work from home
- the kids got to a point where they were more interesting (sounds brutal but let's face it, babies are boring and if you're an alpha man, which would you choose - a night schmoozing clients or staying in to play peepo. I wish my DH could have loved every minute of the baby phase, but good grief, I didn't and regularly wished I could escape so I sort of get where he's coming from)
- he realised that his lifestyle was making me unhappy. And me being unhappy meant that he was unhappy as home life wasn't a good place. He realised that he could live with life like that forever and potentially get divorced or he could change.
We are by no means perfect now, but things have improved massively. I think you need to lay your cards on the table. Tell him what you need from him. Ask him if he will go to a therapist with you (it really does provide a good neutral place to clear the air). Think about the alternative - would life genuinely be better without him there? Ask him whether his life would be better without you there? Explain in very clear terms that while you deperately don't want to split up, things have to change. Finally, have a plan as to what you'd like to do. Tell him that you will be going to college/get a job/volunteer - that you are also entitled to a life.
