Me and my NP are getting married come the end of the year. It's changed from a simple commitment ceremony to legal marriage. His other girlfriend, my meta, is all for it. The three of us live together and we all discussed how nothing much would change within the dynamic.

Well, a guy I've been dating for a few months saw my post on Facebook and has been rather unsupportive lately. He keeps telling me that this changes our relationship and that I'm no longer practicing relationship anarchy "correctly." Every day, he demands (not asks, demands) me to reassure him that we are still good.

At this point, I'm exhausted from him. The constant insecurities that he tries to place on me is infuriating. I'm not even his only relationship. He has his own NP. But he doesn't believe poly people should be allowed to legally marry because that causes couples privileges and such and it's "unethical to bind yourself legally to only one person if you have multiple romantic relationships" (his words, not mine).

Is this the type of response I'm going to get going forward with other people I'm going to date. Because if it is, at this point I might not ever try again. I had to break things off with him last night because it was just too much for me to emotionally navigate and handle.

Please tell me this isn't what the majority of people believe or think. I request (politely) some stories from married poly people on how they navigate this or even some thoughts about marriage and poly in general.

I need to know I'm not alone in thinking marriage changes nothing if that's what the married couple decides.
