What can "she" do? The problem is not with her or what she can do. The problem lies in what you can do and what you are actively doing about it. You are not willing to work on your own issues. Worse, you are not even honest and were pretending "I acted like I was all better and got "cleared"".

Until and unless you are willing to work on your own issues and what is happening with you (e.g. the compulsion to seek multiple affairs from partners other than your wife, your inability to trust, your inability to feel loved) you will never be emotionally satisfied in any relationship.

It's not enough for you to say you love her. Words are cheap. Instead, look at what your actions are actually showing her.

You are very lucky that your wife decided to stay with you. If you want to save the relationship, I would advise you to work on yourself, otherwise she will be fed up to keep giving in what seems a one-sided relationship where your wife does all the work - knowing she is the one who was betrayed by you in the first place.
