Has she gone NC with the person she was texting too?
Never ever cheat again. Delete all contacts with these other women completely and forever. Never contact them again.
Go to marriage counselling. Get the book "His Needs/Her Needs" and the "5 Love Languages."
GET BETTER BOUNDARIES (cause yours suck).
It really took me a long time to be able to open up to her. Aside from the shame of it, I have always been the type to keep things inside. A big part of my actions are a side effect of depression. Until recently I was in denial. With my wife's help, we were able to explore many of the things I was thinking and feeling before and during my infidelity. I am guilty of using the old "I don't know" phrase, but I realized that saying IDK doesn't solve anything. Its important to find what the root of the problem is in order to fix it.I commend you for opening up to your wife. I am on the opposite end and my husband is like you were but he does not talk to me and when I ask him why he does these things he just says I don't know , I don't want to as if that makes sense.
