My boyfriend and I have been together for 4 years. He has a porn addiction which I found out at the beginning of our relationship. I decided to stay because he accepted to work on it and go to therapy, and he did. He has progressed and tries not to watch porn anymore, but once in a while he slips and watches for a few minutes. He knows it's a boundary for me, especially knowing his past (sexting, flriting with girls, etc.) I've told him many times that I just want honesty. I know he's working on the addiction and he's progressing, I won't judge him if he accepts his fault, but I can't trust him if he hides things and lies. But still, he hides it every time he relapses, and keeps lying until he realizes I have proof. We don't live together but I've spent a few days at his house this week. I've looked through his phone and found out that he watched porn twice last week. I've been waiting and given him an opportunity this whole weekend to say something about it, so I didn't say anything hoping that he would open up. But once more, he hasn't and he's been acting as if nothing happened. I'm thinking of just breaking up over text when I leave tonight, saying he has lost his last opportunity. If he can't be honest when that's the only thing I've asked him to, why would he even deserve to have a conversation?
