Search Results: dating a guy that has slept around

There are 2 in particular that have remained family friends. I do not expect my brothers to stop associating with someone just because we didn't work out. Besides there was no "serious" feelings envolved either time. We just weren't a match.

My brother-in-law is a local musician and these guys date other girls now and take them to his shows and even come to Christmas and Thanksgiving at our house. I don't have a lot of dealings with them, but I am not rude when I see them, and I do not go out of my way to avoid them. I'm just indifferent.
I've been dating my new boyfriend for a couple of years and he is pretty jealous anyway. But just recently he learned that I have went on dates with these guys before now my life is extraordinarily boring and lonely. We are a pretty close family. Now he doesn't want to go to holidays or family gatherings with us anymore and gets furious if I do. I can no longer go to my brother-in-laws shows. But the worst thing is how he accuses me of keeping them around on purpose, so i will have someone on the backburner, incase I get mad at him. That hurts a lot because it shows me that he really doesn't know who I am after all this time. Plus I am sad that HE feels like I would do that.
He has an exwife and child that I may always have to deal with, but I accept that... even though he talks to her regularly AND I even found out Later that had slept with her a couple times when we were first together. If I DO say anything about it, he tells me stop bringing up the past. I don't think It is fair that I'm willing to deal with that but he thinks I should have to cut off my family or give them an ultimatum to cut their friends off or I can't associate with them anymore.. even on holidays. I love him but I am getting so sad. I feel stuck between a rock and a hard place. What should I do?
