in my eyes, if he’s ok breaking that rule, he’s ok pushing other boundaries too. the fact that yall have talked about this before and he STILL did it is icky. i suggest being firm with him, let him know he fucked up. idk maybe after talking with him you’ll get a better feeling for whether or not you want to forgive him.
sorry to say but if you brought it up to him once and he disregarded it then he doesn’t respect you or the relationship. I had a boyfriend who kept going back to 🌽 even after I had multiple talks with him and told him I didn’t like it. Eventually it wore down the relationship and i ended things
it’ll be tough but not impossible. reach out to friends and family for support. it’s gonna suck for a few weeks but you’ve got this. choosing yourself over an unreliable relationship will be much easier than staying until you’re too destroyed to stay anymore. i’m so sorry this is happening to you. if you stay, he’ll continue to do it and might even get worse. you deserve someone that has more self control and no wandering eyes.
