I have been in a committed, monogamous relationship for 2 1/2 years to a woman that I love. She was married for 17 years before we met, and I was married for 19 years. When we started dating, she told me that she had had an affair on her ex a few years into their marriage (and he was the father of one of her children even though she stayed married). I recently found out (through a family member of hers who has axes to grind) that she also had another affair several years later (and insinuations of even more affairs - I didn't want to dig too deeply). When I asked her about this, she was honest about it, but got very mad that I would ask (or that I found out - not sure which). I know her ex and I know that he was an extremely self-absorbed person that no-doubt ignored her and the marriage, but that still, at least in my mind, does not make affairs right. I try not to be judgemental, but even though my ex an I didn't have a perfect marriage (obviously LOL), I would never have even considered cheating on her nor do I think she would have.
I guess my biggest concern is am I being too uptight about my gf's past? I don't care how many partners she had outside of her marriage, but the fact that she violated her vows while she was married makes me hesitant to propose to her. Our relationship is an equal, committed, appreciative, respectful relationship, all of the things that neither of us had in our marriages, but some part of me feels like I cannot trust her if we get married. She has never given me any indication of being unfaithful to me and we are very honest with each other about everything, but I don't want this to turn into a deal breaker for my chance at being with someone who loves me and who I love. Am I just being silly and insecure, like she says? If so, what's the best way for me to get past this?
Thanks in advance
