Hi, well I think you have answered your question. The answer is YES!!! you have admitted you have problems and now its time to get help. You will also need to give your spouse some "time" to herself. This is no excuse for her to cheat on you. She needs help as well. I'm thinking she has not felt great emotionally and that can make people "easy pray" your good friend is not a friend at all. You will have to find a way to really forgive her and she needs to forgive you so you two can move forward repairing. Your wife will start to see the changes your making and you will need to really make changes. I think its going to be hard at first but you will need to controll yourself and not allow anger and frustration to come out. This is the time you will need to be open for things you have not done before. I think you two will need to try a date night at least once per couple weeks and really make it special. If you really want this to work in your heart and soul, you can and will. remember you can only control you, dont try to control her. And please give each other some space. I do really wish you the best.
