moving in w a male friend

I (F21) am contemplating moving in with my friend (M22) from high school. We’re about to be in our last year of college, and he just transferred during his junior year. Since he just transferred, he didn’t have an apartment for junior year, but is currently trying to find one for senior year. I am also in the market, as I have been living with several roommates, and it has finally caught up to my social battery. Even though I love my friends, I think I need to live with less people. In the case of moving in with my high school friend, it would just be me and him vs me and 4 others, which was very draining.
Ever since we brought it up, I feel like it would be a perfect situation for us both- we are both clean in common spaces, the rent is both in a perfect range for us, we’re both in relationships and fine with each others partners coming over whenever, and we both have cats! We would definitely have no issues living together.
However my only issue is that I want to bring this up to my boyfriend without making him feel uncomfortable. Im truly interested in this housing situation for the benefits of living together. Me and my friend both seem to be on the same page with everything regarding living together. I really don’t think we’d have ANY issues with each other and it honestly might be the best scenario for me atm.
I’m just worried that this might be uncomfortable for my boyfriend, but I don’t want it to be. I’m curious what I could do to make him feel comfortable, or if I just shouldn’t do it. My bf isn’t overly possessive, just might feel a little awkward as we’ve never been put in a situation like this. We both have a lot of trust in each other, but I don’t want to damage it with this living situation. Do you think it would be harmful for just the final year of our undergrad to live together?
