You are actually in a better position than you think. First off, she isn't taking steps toward separation or divorce. I realize that doesn't sound too comforting right now as you are feeling very alone in your marriage at the moment, but what her LACK of actions tells me is that she isn't commmted to leaving the marriage and is (in her heart, deep down) tryig in her own way to save it. her saying "i don't love you" is really a cry for help, imo. So, SHOW her that you can be a great husband and father. LISTEN to her when she askes for specific things that she needs. She is probably scared right now and I'm sure confused. The stress of what you guys have been through is playing itself out.
I think her wanting to go to therapy is great -- yes, she's saying it's for the kid, but I'm not buying that. I think she also wants and realizes that NATURALLY the therapy WILL turn into marriage counseling sessions. You have a BABY, not a 12 year old with "issues". Give me a break -- she's using that as a cover story.
And I agree with the above. Make her accountable. If she doesn't feel that she can sleep next to you, make her feel the consequences of that decision by having HER sleep elsewhere.
