i guess tree if the thought of another man being with your wife is the final straw of yours then yes you can let go. if and only if you feel that if she came back and was the wife she was when you were happy then hang on. realy you have nothing to loose by being open to a future. if something else does come along then fine dont hold back. but untill it does you always have a chance with your wife. the LRT is what I would recomend but5 i am NO expert.
