How would you feel if your boyfriend lived in a house with 3 other women?

My boyfriend is moving away and although it is financially and physically possible for him to live on his own or somewhere else, he is choosing rent a room in a house with 3 other women... women that he doesn't know and neither do I. I know he would never cheat on me and his purpose for moving to where he did is for work. He is there for over a year. He knows that this is absolutely killing me that he is living with only women in a fairly small house. He also knows that I would do anything right now to be able to move in with him and start our lives together. So I am naturally very jealous that he gets to have his first experience living on his own with 3 women neither of us knows. I am willing to put up with it because i know it is important for him to be there but I would like to know if I am being out of line for wanting him to live somewhere else or if he is being selfish by completely ignoring my feelings. I have talked to him about this in the most heartfelt, respectful way and he refuses to even consider a different living situation. Thoughts please.
