Okay so my boyfriend, (ex boyfriend right now but we are working on that) just joined a fraternity a couple of months ago. I told him to do it, that it would be a lot of fun but honestly it has been nothing but hell for us. I have been in my sorority since we first started dating (we have been together for a year and half) and he used to be so insecure about me going to socials and parties without him so I wouldn't. We spent all of our time together and were so happy, he was the best boyfriend I have ever had and has treated me like a princess from day one. Well once he joined this frat, he has completely changed. He wants to party all the time, he started smoking cigs, and he has gotten fired from his job because he wanted to hang out with his bros and forgot he had work. On top of that, he recently dumped me because he just feels like he wants to be independent for awhile and doesn't want to have to check in with me all the time but he says he has every intention of us being together again. He dumped me right before his formal but still wanted me to go because he "couldn't imagine taking another girl" but he treated me terribly while we were there. Whenever I would walk into a room he was in, he would tell me to stop babysitting him and leave the room. I would simply walk into the room and he would that... It got so bad that I literally packed my stuff and left. The next day he apologized and said he just drank too much and he knows he messed up and blah blah blah. I am just so confused. I don't know what's going on. This guy is literally my best friend, he knows everything about me and I know everything about him; we spent every day together and were ALWAYS happy. He talked about the future and getting married and I never imagined us ever breaking up (he said he never would break up with me). Why did he just dump me out of nowhere then? I am so confused and beyond stressed about this entire situation, I just don't know what to do. Is this just something he is going through that will end soon? His personality did a complete 180. oh and he rushed as a junior and he is pre-med but his grades are no longer reflecting that but he says he cares more about having fun then schoolwork and grades! and he promised me that if this fraternity was affecting our relationship then he would drop. When I asked him if he remembered that promise, he said "Yeah but you've broken promises before. I'm not dropping." What is going on??
