So my SO and I have been together for a while and are thinking about moving in together. My rent starts in August (we will be together for 1 year and 8 months at that point) and I will be living with 3 other girls. One of my roommates is my best friend and she would be so excited for him to live with us. One of the other girls wouldn't really care either way. The last roommate we don't know who it is. Do you think this would be too complicated of a situation or do you think it's a good idea? Any suggestions?
