I Don't Like Where My Boyfriend Is Staying

So I started spending the night at my Boyfriend's apartment. He is roommate with a girl who I recently found out is a stripper. The second I got their he gave me rules. If food has a pink sticky note it's hers, blue it's his, and no sticky it's free game. Told me not to really talk to her when she gets off of "work" because that's when she decides to hate her life. And don't go in the hallway closet. Everything was ok. I was friendly with her even though I was still pissed shes living with my boyfriend as a stripper.

So yesterday my man was at work and I was looking around. Don't know why but I decided to go into the closet and there was a box full of dildos! Dildos, vibrators, etc. It may sound dumb but I was pissed this was in the house with my bf. When he got home I tried to talk to him about it. He said you should have listened to me now let it go. I asked how I was supposed to let it go. He goes, what she does is not your business nor your concern. I pretend it doesn't exist and that's working for me now let it go. I again bring up saying he should just come live with me. He again says a few months isn't enough time together to move in. I'm seriously starting to think he isn't serious about this. Plz no hate comments but what do you guys think
