<human>: I know SO has been in open relationships in the past, and I am only his second serious relationship period in his 49 years. A couple of weeks ago, we somehow ended up in a debate about monogamy - I am strictly monogamous, and he seems to think monogamy is ridiculous; humans aren't meant to be that way; that if you love someone, you should give them every freedom, not bind them with rules; etc. He did say that he wasn't speaking about us (we have been in a monogamous two year relationship), and that's the part that has me thinking.

There seems to be a disconnect here - while he may not be speaking about us right now, how do I know he will continue to be monogamous, but more important, be happy with monogamy in another two years, five years, whatever. For me, non-monogamy is a complete deal-breaker.

I don't believe his views are inherently wrong, but they are just not for me. I'm not sure what I'm asking here... I know I need to talk to him about this - but part of me fears that this conversation will mean the end of our relationship bc he will say that he can't guarantee me monogamy. Maybe I'm trying to understand where he's coming from by asking those who share his value on this about whether or not you can guarantee your partner monogamy.

Thanks.

Could you distill the essence of the text into 1-3 sentences?
<bot>: SO debated me about monogamy -  he doesn't believe it in. I am strictly monogamous. If you are nonmongamous or have been in a similar situation, was your partner able to guarantee monogamy to you?
