Think about how women in abusive relationships slowly wake up to that realisation. It often takes YEARS even for someone that could be described as the sharpest tool in the box! Following a bit of research (not extensive, nor official, more a straw poll) it appeared that ONCE discovery/identification of the fact that the marriage/union ISN'T healthy, it took the women spoken to TWO YEARS to actually get the courage, conviction and wherewith all to get out.
This man has been posting for 2 years, he's beginning to come round to the inevitability of the situation he is in. Of course he doesn't want to end his marriage/relationship, none of us do, even those in HIDEOUSLY abusive situations.
All we can do is keep supporting him, keep reminding him that this is NOT his issue to fix anymore, and that he is entitled to be happy.

don't ever think compassion, understanding or sympathy will run out, it won't, not collectively. Mumsnet is bigger than that!
Please understand that you have a RIGHT to be depressed, you are unfulfilled, you are not being nurtured, either by yourself or your relationship. you have no way of expressing this effectively so the frustration has turned to anger and then in on yourself.
Know that WHEN you realise that enough is enough, leaving/separating WILL go MILES and MILES to 'cure' your depression. You are in a vicious circle at the moment, and until you break this pattern, you will stay stuck, growing weaker by the day.
be brave. Think about how your life is now, could it get much worse? Then DO something different, make the change and just see how things go. If you separate and then decide that it was a mistake, you may be able to go back, but I think (and I feel certain you know) that once you leave, that will be that.
Perhaps that is what needs to happen, your resistance in moving your life on is slowly killing your spirit. Life is too short to be this miserable.
