This is my first post here, so sorry if I say something that should be obvious or make some kind of stupid faux pas.

I see polyamory as a part of my identity. Monogamy has really never been "a thing" for me, I never got it, and I've largely kept to relationships with like-minded people.

However, my current SO thinks differently. We've been in an open relationship for a while, with the rule that we "can't really get serious with anyone else". However, they didn't know I was poly when this arrangement was made. I have since explained to them, and stated that I would like us to relax this rule a bit, and explained that I won't have feelings like I do for them for anyone else.

I've talked it over with them many times, and they keep stating that they're OK with it... But they seem so afraid that I might just trade them for someone else (completely impossible, btw, I love them devotedly and despite the possibility of me having feelings for other people being well and alive, it will never be the same as with them)

I don't want to hurt them, but at the same time I find myself unable to completely stop myself from having feelings for other people I become involved with. Should I just suggest we go monogamous and try to live with it? I don't see many other solutions.
