It's not really important but I need a bit of help

For quite a while I have been feeling really shit. I'm always tired but can never sleep. I started talking to this guy that I work with and we were getting along really well, we started getting pretty serious but never said that we were dating. Anyway, his best friends next door neighbor is one of my good friends. She invited us all to go to her house for a few drinks, this is the first time me and him had sex. We started seeing each other every weekend and I ended up being invited out with him and his mates for his birthday. Me, him and his brother were all sharing a room which was fine, there was 2 beds so that's all good. When we got back to the hotel after drinking all night, it was about 5 am, I just wanted to go to bed. That was my main objective. I got into A bed and tried to go to sleep but kept waking up every 5 mins and seeing what was going on. He was lying in the next bed and his brother... Well his brother was next to me. He must have woken up and seen me with his brother because he got up and left the room. I got into his bed and left his brother where he was. I thought everything was fine, he was fine with me the whole week. Until it got to that weekend. We got invited back to my friends house, after he said that he was worried about me and needed to see if I was ok. We were in the spare bedroom talking till about 6am. Then out of nowhere he said "you friend it on with my brother, don't try and deny it I saw you" I was being so brave. I kept saying sorry and asked what I could do to fix it even though I knew I never could. He went to sleep and I stayed awake for another half an hour before gaining the courage to get dressed and tidy up. Just as I was moving my bag, he said we need to talk. We carried on the conversation and at the end of it he lay me down next to him and held me until I fell asleep. We went back to his where I slept even more, and then we decided that we were not going to be seeing each other anymore. I didn't cry for the whole of the time I was next to him. But as soon as I got in the taxi to go home, and he closed the front door to his house, I burst into tears and rang my best friend who tried so hard to calm me down. I went back home and cried more, I had a shower and went back to bed. Baring in mind this is about half 4 in the afternoon. I didn't wake up again until about 1am for a cig and then went back to sleep again.
