<human>: My current bf and I have been together 4 months. I'm bisexual and open to non-monogamy. He is straight and highly values monogamy.
He's great guy and 95% of the relationship is open and fun and caring. 

In my previous relationship of 2 years, I spent some of it being non monogamous. It was the right decision for us. It worked out well. We both liked it. We broke it off for other reasons.

I do not feel that I need to be non monogamous to fulfill myself. I'm open to it, yes, but I don't crave it either.

My current bf has expressed insecurities about my bisexuality and my experience with non monogamy. He says he can't fathom how I could do that while in a committed relationship. He views it as betrayal. 

I've told him time and time again that I don't need it, nor do I want it in our current relationship. Did I enjoy it previously? Yes. But I don't need it now to feel fulfilled. Would it be nice? Sure, but I don't need it.

It's gotten to the point where I've explained myself so many times that I'm feeling upset by it. I don't feel like I should have to continue to justify my past, and I don't feel like I should be made to feel bad about it.

He says he doesn't want to make me feel bad. He's just insecure and wants clarification.

Am I in the wrong? Is he in the wrong? Does that matter? What can I/we do to make this right? He's great in so many ways. It's just this hiccup that's getting me stuck

Can you provide a brief overview of the text?
