I agree with Bella01. At this point, you shouldn't be thinking about rebuilding a marriage or anything other than getting you in a better place, and I mean that above and apart from being in a relationship. If you're not better, than what really do you have to give to your marriage should you reclaim it for an improbable third time.

May yourself into someone a woman would want to be married to and then the right person will come into your life.
