<human>: My boyfriend and I have been dating for almost a year now. We are very content in our relationship and I am extremely happy. However, I recently found out that his living situations for the fall have changed. He was originally planning on living with another guy friend and our mutual female friend, but his guy friend had to back out last minute.  Unfortunately, student housing is becoming scarce and I know he is starting to get stressed out about his living situation. He has mentioned trying to find a 2 bedroom apartment with our mutual female friend.

I can honestly say that this makes me uncomfortable.  It's not that I don't trust him or her; I honestly do not worry about him cheating on me. It's really just the principle of the matter: he's living with another girl. 

So, what I am debating is telling him how I feel. On one hand I feel like I am being unreasonable.  I'm not concerned with infidelity, so why should I say anything, right? But at the same time I do want to say something because it hurts my feelings that he would be living with a different girl, even though they are just friends.  What should I tell him if I decide to tell him how I feel about the situation? I do not want to be unreasonable, especially because I know it is already stressful for him and I also do not want our female friend to not have a plan for where she will live. Please post your advice.

Give me a shortened version of the text
<bot>: Boyfriend is considering getting an apartment with another girl (mutual friend). Should I say that I am not totally comfortable with it or am I being unreasonable?
