Giving up on my marriage....

So, I've been really busy at work. I'm trying to go to the gym 5 days/wk for an hour after or before work. I'm stuck at 124/125 lbs and haven't lost in a while, so I need to do some heavy restricting this weekend and for the next two weeks.
My marriage is so totally gone to shit.... I've stopped caring and so has he. Everything about him either pisses me off, disgusts me, or annoys me. The thought of sleeping with him just bothers me.... I'm working on moving out. I want to be able to get some computer certifications in the next six months and get a higher paying job or a raise, enough to support myself.
I'm not going to bring it up to him till I'm ready to 100% leave him and never look back.

Living with him makes me miserable and I just want to move on..... get on with my life.

I use to not want to leave him because I was still in love with him and I couldn't stand the thought of him being with another woman, but now I don't even care. That's how much I've fallen out of love with him. We haven't even reached our three year anniversary..... its a good thing we waited on the kids.
