I feel for you, this sucks, no way around it. My sitch is similar but a little different, I have 2 small kids and wife admitted EA/PA, says she is in love with OM. She moved out about 4 weeks ago, said she needed to figure out her feelings (for OM apparently), I told her that I would not be in our marriage while she 'dated' another man, both been to attorney, should have paperwork filed next week for divorce.
You're young, you don't have kids, ask yourself if this is really the kind of woman that you want to spend the rest of your life with? My wife had no respect and no appreciation for me, I decided that I deserved better and have been GAL'ing.
You need to ask yourself the hard questions, why are you hanging on to this woman?
Check out this book, it was a huge help to me: No More Mr. Nice Guy.
