So I don't know where to start really.
I have dh and 3 DC's. Dh and I have been together 8-9 years. Looking back I think only the first 4/5 years were good and the rest have just happened iykwim...
He used to be so outgoing and funny and he would make such an effort with other people and me. He had such drive and passion for his work and was very get up and go - all of these things are what stole my heart.
Now he sits on the sofa, on his phone playing games, moans about his work (and has been through several jobs in the past few years as well as being unemployed for quite a lot of time) and not really understood when I've said he just has to get on and not quit as we have a family. He isn't chatty to other people, it's quite embarrassing at times actually. He can be rude. He doesn't play with the kids and it seems like he feels that they're a big inconvenience for him. When people ask him about kids his answer is always 'a word of advice, stop at 2' 
He doesn't exercise, socialise, want to do anything. He complains that I arrange things for us to do. He says I make him miserable and treat him like shit but yet because our home phone wasn't charged the other day I was asked 'what the hell do you do all day??'
He hasn't had affairs that I know of but has had dodgy relations with females (meeting up with innocently apparently but failing to mention to me about it)
I'm just a bit lost really. I think he's depressed but no idea how to help him. He doesn't believe in meds for depression and won't go to the dr for anything at all. I have said all the above to him during a row but he just doesn't care. He says he'll just put on his fake smile and get on with it. I can't stand it any more 
Not sure what I'm after tho opinions would be nice I think?
