I have an ex with whom I have a 6yo with. We have broken up a few times but after the breakup we start having sex again after a couple weeks or more and that has led us back to trying to fix the relationship. It doesn't work out and the cycle continues. The sex is great and familiar, we still love each other but a few key things keep us apart.. I can't be relied upon to be the one who says no. Besides a rebound encounter, what have you done in the past?
