Hello, it's my first time posting here, which I think is the right place to ask for advice, Here's the thing: I've been in an open relationship for the past year and a half, on and off. We had set some mutual agreements and rules for it. They all come down to prioritizing each other over anyone else as well as time together over random encounters with other people, but he's broken all of them at different points, the last one being yesterday when he saw another person and had sex with him right before seeing me, when we had agreed that we wouldn't be seeing anyone else on the same day we'd see each other (before or after).

We almost never have sex by now, I think it's been only once this month. I feel like he always prefers intimacy with others rather than me. He says that there are more important things than sex, which is true, but it doesn't change the fact that it's important as well, at least for me, and that I end up feeling neglected.

Yesterday I called him to confront him on this after I realized the last agreement was broken, and he excused himself in that he did it for money (although it was with his friend) and that the agreements were set in a different context and things change. Didn't say sorry, didn't try to fix it.

I said that we either close the relationship, or I'm out, because he's the only one benefitting from it being open (I work and study full-time, most of the free time I have I spend it with him out of respect for the agreements, but I never get to see other people). He said he understands if I want to take some time, but doesn't think he can be in a closed relationship, and I hung up and blocked him. I felt like he confirmed what I thought, that whenever there was a choice between others and me, he'd always choose others without any hesitation.

I understand we might have different needs, and before all of this I was thinking of proposing him a scheme where we could close and open the relationship in 2-3 month periods or something along these lines to meet both our needs, but this made me realize any agreements we make, aren't respected, and any similar plan or type of relationship could only work if we both follow on them.

I still kinda feel like I was acting out of anger, though. Was I right throwing away everything we built these past two years like this? I just feel like I can't anymore with this.
