Yes, we all know it's a good idea to put the past in the past and start over again. But remember that means you will have needed to have already completed the work you need to do or are actively doing it now. I mean seriously, major emphasis on correcting the opportunities with you. Second your wife needs to feel like she's ready to do that too.
Best thing for you my friend, smile, be happy, don't be overly affectionate, needy, clingy, etc. Be confident, happy and above all act as if your pain doesn't exist.(Fake it til you make it if need be.) Give her someone she can be comfortable around and eventually the wall will start to come down brick by brick.
If we really want to love, we must learn how to forgive. - Mother Theresa
