How do i get him back?

We all make bad judgments from time to time, that is what gives us life experience. You are in a relationship that you make sound like it is over. Does your husband feel the same as you, or have you become so infatuated with getting your ex back, you have allowed your current relationship to dissipate without trying to fix the problem? If that is the case, your current spouse deserves to know and have a life of his own. Or are you keeping him "just in case?"Try and speak with him and see if he feels the same as you.Of course ,you may end up with no spouse, and no new relationship with your ex. Your ex is just married, so you trying to slide into his new life may be a mistake, he is married and probably in love with her. If you do proceed and manage to break him apart from his wife, it is you that has to look in the mirror everyday and deal with your conscience.
