I have to tell you, I'm just a little ahead of you on this awful timeline (my H left 2/12/12). I think there must be some kind of wall we all hit - where reality is starting to smack us in the face, and the wallowing we've been doing isn't making the separation any better.
I know that I'm having a hard time with the same things you wrote - he's not the person I met and fell in love with and the constant lying, not to mention the constant rumors of the OW (and the lies associated with H trying to cover that up). These last few days have been feeling especially hard to fight for my marriage. But, I remind myself that I'm not fighting for this marriage, I am standing for my marriage and the promises that I made to my H in front of all our friends, family, priest and God.
I know it's hard and I really do believe that it's the timeframe we're in, and we haven't gotten the complete hang of DB-ing yet. Try to take things slowly as you want to be sure that you don't have any regrets in the future.
Give yourself a break and do something nice for yourself - you certainly deserve it.
