There’s something your wife can not provide. What was the reason of breakup if you still searching something that you miss. No one can prison your mind but it’s call infidel in another form. What a joke because we miss our Cavalier King Charles Spaniel Christmas tree shirt and tired of the one we’re with? If you’re tired of the one you’re with, leave and move forward, going backwards is idiotic they are ex’s for a reason. He wasn’t with Sarah when he bumped into her, she just thought he was. People relationship get ruined because of the other going back to them. I saw my ex the other day would have loved to punch him in the face. I still see my ex every now and then.
