I fucked up massively and massively and I seriously don't know what to do, I feel lost and like I'm better off dead.
I've been going to college for 5 years. 3 Semesters ago I met a guy who went on to become one of my best friends. This last summer he moved into my apartment (along with 3 other guys) near school, and as soon as we started living together things went to shit. We began getting in constant fights and butting heads about everything. He got a cat even though our landlords explicitly said no pets, but I let it slide because he promised to pay any fees if the cat was discovered. I began having breathing problems and realized that I was badly allergic to cats, but he would not get rid of it. I knew he was kind of an asshole sometimes before he moved in, my first clue was when last year he purposely forget his new girlfriends birthday so that he wouldn't have to buy her a present. Not only that but i discovered that he had been cheating on her with another woman. He is a fairly famous youtuber and has his snapchat listed on his channel, and I also caught him receiving nudes from numerous women and he made no efforts to stop that (he continued chatting with them). That really made me think less of him, but he was still a close friend and someone I saw regularly so I allowed him to move in with me regardless. As my summer went on I grew more and more depressed, living at my apartment made me hate life. I went to the school at 8am and stayed some nights until midnight. I was so afraid to come home because the house was a massive shithole where no one cleaned, I couldn't breathe when I was there (even with my inhaler), and this guy who used to be such a good friend was becoming my biggest enemy. One day, new neighbors moved into the apartment right next to ours. I met a girl who had moved in and she saved me. She made my summer a million times better. We started dating and I was the happiest person ever. As the summer ended and my final semester of school began (im done in december), my depression came back due to my relationship with my roommate getting even worse, and the difficulties of working while taking a 20 credit semester. I spent many nights crying because of how much I hated life, but I knew that I just had to make it to december 20th. Last week my roommate broke up with his girlfriend (the same one he had cheated on). The day after he broke up with her he had a new girl come stay the night (he said they were working on "music" for a video). The girl he had stay the night was a girl that another mutual friend of ours was crushing on for years. Me, my roommate, and this other guy were all very close, but he (after 1 day being single) brought our friends crush over to fuck.
A few days later his ex girlfriend messaged me on facebook asking if I could help her move some things out of our apartment that she had left there. My roommate was cool with it because neither of them wanted to see each other and they wanted a middle man. I helped her move stuff out. Over the next few days she kept messaging me and she was clearly in an emotional state and seemed to really be calling out for help. So i would respond to her and I was sincere and letting her know they things would be okay and that time would heal everything. This past saturday I was up north staying at my families hunting shack, and I was very drunk. my roommates ex was snapchatting me and she started to become flirty. I was turned off by it right away, but then all my feelings of anger about my roommate kind of came to a head and I wasn't thinking straight. I flirted back. She told me that she wanted to sleep with me, and she started asking if I wanted to come over to her place the next night.. I said yes.
The next morning I sent her a message, "Look ______, my head has been spinning all night long and I don't think I can do this. I've been extremely depressed and emotional this semester, and if I committed on any of the things we talked about that it would send me down a very dark path. You're a very nice person, and I'm sorry."
Today I was sitting in my web design class and my roommate asked me when I was coming home. I told him 5:30. Then he asked where I was. I said I was in class on the first floor of Applied Arts (one of our buildings). 15 minutes latter the door to the room opens and its my roommate standing in my class. He motions to me so I go out the door and he says he wants to talk to me. Were both walking down the hall and hes not saying anything but hes leading me to the stairwell. We walk into the stairwell and he says that his ex told him I was flirting with her and sending her dick pics. He said that I have been nothing but a detriment to him, he can not have me in his life. He said he wouldn't tell my girlfriend, but he wants me out of the apartment after thanksgiving. I cried to his face and told him everything but he repeated that he wanted me gone.
Now I have nowhere to live for the next month before I graduate, and all of this has just ruined me and my emotional state right now. I recognize how large of a mistake I made, and I feel just completely dead in the water. I don't know what to do.
