<human>: I [F20] love my SO [M24] and we've been together almost six months now. The problem is I'm starting to feel like we have nothing to talk about anymore. I try to show interest in the games he likes, but they're no fun to me. I don't really have any hobbies because I work ~50 hours per week and I'm a night shift worker so I'm pretty limited in that nothing is open whilst I'm awake.

We have a really similar sense of humor and we like the same music, but six months in we can't really talk about that stuff as much as we used to. 

We never really do anything together, and I worry that the relationship is going downhill because of it. We've started fighting a lot more and I find myself thinking about other men. I would never cheat on him, and I don't want to leave him because he is so perfect and I love him, I can't imagine my life without him at this point. But we have days together where I'm off work and all we do is lie in bed all night because I have to sleep during the day and there's nothing we can do at night. 

We've tried watching movies, but I have a housemate and my SO has bad hearing so we end up having to turn the volume up too much which wakes my housemate and I don't think that's fair on him since he's very quiet during the day for me.

I don't know reddit, I'm confused, what can I do with my SO to give us something new to talk about?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I don't have anything to talk to my boyfriend about and I think that's the reason we fight so much. How can I fix this
