Should I end it with my partner because I don't see myself marrying him as a result of my own insecurities? I don't want to be stuck in a marriage thinking that he's cheating on me. I try not to disclose these feelings to him or let it effect our relationship but its in my mind constantly. I can't get over the fact he didn't tell me he was married, or that he still communicates with many exes. Even though I don't mention it anymore, I've tried to move on but it still breaks my heart a little if I think about it. I know that he truly is a good man and I feel like I don't even deserve him sometimes but I don't want to be his third wife. Can he even have a successful marriage after his first two have failed? I do recognize all the effort he puts into our relationship and I think that maybe our relationship is good just the way it is. I do think he deserves happiness and I'm not trying to punish him by not marrying him. I think we have a strong relationship that's worth something but my insecurities are getting the best of me.
