I haven't told anyone but I'm in a polygamous relationship.

I started dating a guy about four months ago now. He didn't tell me that he was in a relationship with other women until our fifth date. He convinced me to give it a try and I reluctantly agreed but only because I really liked him. I kept going on dates with him and I fell for him. I thought it would be really weird but I am actually really happy with him. I met the other women for the first time last month (they both live with him) and it was really awkward but since then I've stayed over at their house and we get along okay. We're now at the point where I would ordinarily want to introduce him to my family but I don't know what to do. I don't know what they'd think of me if I told them. [Light]
