Was it the right choice? ?

This year was my sophomore year in college and also the year I fell out with my three roommates. They seem to take advantage of me and use me. When I started to distance myself they did try to talk to me but it made me feel worse cause they blamed my feelings on myself that they had nothing to do with it. One of the girls was my best friend and I believe she should have been the one willing to talk but when we talked she just told me she didnt wanna talk (maybe it's just me but if your bestfriends with someone you would wanna talk things out no matter what) things got worse and it got to the point where I just took myself out of the equation and hung with other people friends I had. When they finally did decide to talk me it was so damaged it couldn't be fixed I had already caught them talking about me and figured that I will just them off all together but when we talked I decided that I just wanted to be cordial with them. Was I wrong?
