Add me to the list of people who are wondering why you were on a dating website.
I agree with lovehurts, just because she is talking to another man does not mean she is doing anything suspicious.
I think it is a good sign that you two spend time together and that nobody is filing for divorce. Personally, I feel unless there is abuse, or serial cheating, it's never too late.
Keep your head up, keep going to counseling and working on yourself.
