My boyfriend got a flip phone.

I (24 years old) found out that my boyfriend (27 years old) was suffering from porn addiction. I took it the worst way. I hate to say that I lost respect for him and the entirety of the relationship. We live together now and we lived together during all that. Anyways, I was pretty set on leaving and ending the relationship. The idea of moving back home really sucked but I was just too resentful, disgusted, and hurt that it seemed like the only right thing to do. Somehow, after a lot of talking and crying and me saying stuff to him that was so hateful, I literally never imagined I’d ever speak to anyone like that tbh. He told me he was going to get a flip phone and promised that he was going to quit the habit, that it wouldn’t be a problem anymore if I moved back in with him. He actually did get a flip phone and has had it for over a year. He never mentions going back to a smart phone at all. He still has his iPhone for music and stuff & it sits at home all day. My thing is. There’s just no way that he doesn’t have another phone at work or that he’s hiding somewhere. He works late all the time. And he’s just so indifferent with me. We can never have a real conversation unless it’s about something that’s going on in his life. I make sure to engage, even when he’s just talking about something that happened at work. He has no curiosity about me or anything I have going on in my life. The silence and dryness I’m met with when I literally need support or someone to talk to just breaks me down at this point. I’ve tried talking to him and approached him in every way about how I’m a person that needs and appreciates communication and transparency. But he will just go entirely silent until I change the subject. I just can’t connect the dots. Any insight or advice would be appreciated.
