Polyamory I need help

I'm really open to polyamorous relationships, but I wouldn't actively seek it out.

If my partner was polyamorous, I would be okay with it and I might even start to fall in love with their other partners, but if my partner was monogamous, they would be enough for me. HOWEVER- if someone came up to me and told me they liked me and I had a monogamous partner, I would put the person on hold, decide if I would like to date them or not, and talk to my partner about it. if my partner is okay with it, and I like the person, then I will ask the person if they are okay with polyamory. if my partner is not okay with it, or I don't like the person, then I will say no. any clue if I'm polyamorous or if I'm something else?
