Recently me and my girlfriend of a year and a half had a big arguement because I told her that me and 3 of my guy friends and one female friend would be renting a house together. I have known the female friend for over 3 years, and nothing has ever happened between us and nothing ever will because there is absolutely no interest on either part. We are all jsut one big group of friends. Am I being unreasonable thinking she should be ok with this? Would any of your SO's be angry in this situation? She is incredibly angry, but I think after a year and a half we should be stronger than this... SOrry, I am kind of ranting.. any opinions?
