You're not going to get a lot of sympathy for your situation due to your actions, I'm afraid; most of us are here as a result of our spouses having emotional or physical extramarital affairs, and that is something that is not taken lightly. My soon-to-be-ex-wife (STBXW) and I started our marriage as a result of our own affairs in our first marriages; something we have regretted to this day, and something that played a very large role in the impending death of our marriage.
Your wife has no respect for you and does not trust you; probably never will. That is the death knell for most marriages. All you can do is work on your own issues for yourself, and don't even think about possible reconciliation. If that would happen, that is a big bonus.
