Welcome to our forum.
Sounds like you're in a pretty nice poly relationship, although I'm sorry to hear you and your boyfriend were unable to come to terms. Sometimes it just happens ... monogamy is not for everyone, and the same could be said for polyamory. You just have to find out what's right for you.
I'm glad you could join us, and I hope your stay on Polyamory.com is a pleasant one.
Love means never having to say, "Put down that meat cleaver!"
