Newbie seeking some experienced advice

[nick77]

Man this is impossible. I've been fine all week and felt really encouraged after a couple nice interactions with my W earlier this week. Then this morning I had to take some papers to my W that she asked for and needed ASAP and when I got to her house I saw the other guy was there. They work together and just finished a night shift. My heart sank and I just wanted to die. I guess inside I was hoping she would stop seeing him since she just finished telling me she doesn't know what's going to happen between us.

I'm seriously working on myself. I'm going to counseling weekly, exercising regularly and losing a ton of weight, hanging out with old friends that have kids my son's age, meeting new people, etc. But I can't completely detach. I want to and know I need to but I'm constantly thinking of my W and her being with another man. It's killing me. I don't know what to do next. I'm not going to say anything to her about him being there or engage in any arguments but I can't stop feeling like I'm dying inside. Does it ever get any easier?

I know people have turned marriages around but I can't see it. I don't see how I can ever do anything with him in the way. I'm so lost.
