Question/ advice

Throw away account.
My wife and I separated for a brief period. While we were separated. she slept with another man. I knew about it the night she left because of the camera. She went to his house. He never came to ours. We both started therapy and have tried to work things out. When we first talked about getting back together she trying to tell me what she did but couldn’t get the words out. So I told her I already knew that she had slept with him. She didn’t know I knew and was a little shocked by it.
She later told me her therapist talked to her about this before we talked. That she has some issues with self worth as a women and she seeks validation from men to help her psyche.
I’m trying to do my best to improve myself for myself to be a better man and husband, but is there anything I can do to help her as well without seeming like I’m being overbearing or stepping out of line.
