Broke up with my boyfriend over porn.

Since we started dating I’d been really open to my boyfriend that I am not ok with porn in a relationship. There have been several occasions early on where I would find out he had done it behind my back and he promised he would never do it again. It’s been months and I’ve been under the impression he doesn’t do it anymore. He’s told me straight up he doesn’t and hasn’t since then. I thought he understood how much it hurt me, I have BPD and certain things like betrayal will set me off into a rage.

Well, today we got in a fight earlier about unrelated matters over text while he was at work. He guessed I went home but I actually stayed at his house. When he got home at 11PM, the house was dark and he assumed I wasn’t there. I heard him talking to his cat about me and he said “just have to piss her off and she’ll leave” I honestly just wanted him to feel sad for a sec and then come out and everything would be fine and we’d make up. No big deal. But instead I walk out after a few minutes and he’s sitting there on his phone looking through porn.

He at first hides his phone and acts innocent like “omg you’re still here?” and I told him I saw it. He kept saying sorry and “I was horny”. We had sex the night before and have sex every single day. I felt like absolute shit.

I know a lot of women on here won’t agree with me but I don’t really care. When you set boundaries with someone that they agree to, and they break them it’s not ok, let alone multiple times. I got lied to for months and I was completely unaware, that is what he would do everyday when I wasn’t there. How do y’all feel about porn in relationships? Is it not a big deal to you?
