Does she really question your dedication to her? It sounds by your description that she needs you to prove your independence not dedication. Find some hobbies, give her a little space, but not too much. Continue to let her know you care about her but show her that you are your own person. Nobody likes desperation, its a turn off. It is hard to be the only thing in someone's world too. I've been there. It's a lot of pressure to try to keep that person happy and it requires a lot of self sacrifice to attempt it. Continue with counseling and REALLY listen to your wife. Hopefully she'll tell you what she wants.

ok, i'm going to take a wild leap and assume that if you didn't cheat on your wife she has reasons to believe you did. I don't know what advice to really give you but I can give you snipits of what it's like to be the betrayed. When I found my H had cheated on me my world had hit spin cycle. What was up was down and vise versa. I found my husband's affair when he was at work and i was at home. He rushed home and we talked about it. He then had to return to work and I went to sleep... or at least tried to. I'm not really sure about the next few days-think i've mentally deleated them because they were so painful. I go to work and so does my husband but we're on different shifts. I was given time where I didn't see him and immediatly think about the affair. It sounds like your wife may need some time away from you to simply have have the affair(?) be the first thing on her mind all of the time. It can be rather exhausting. Duped does have some good advice in trying to find things (healthy that won't cause further damage to your relationship) to help you too release some of the energy. Give your wife room to breath so she's not feeling smothered but actually wanting you to be by her side. Good luck!

Ande421- She is the one who stepped out side of the marriage. "Just talking and a kiss" I would not have done this to her.
