Here is the run down of the mess that I'm in...

I know this guy, Friend O, for about half a year when school started last year. Now things were always...kinda flirtatious between the two of us. He'd flirt with me and I'd flirt back, but we never took things to the next level; it was all in good fun. Then in October, I got a boyfriend and didn't flirt as much with him as before, however we still flirted from time to time. When the boyfriend broke up with me a month later, he helped me out through a couple of tough spots and I started to develop feelings for him.

I also have another friend, Friend M, whom I've known for about...six years. She goes to a different school, so our friendship kind of drifted apart. Also, we've had a couple of arguments and misunderstandings between the two of us, so our friendship wasn't as great as before. However, we were still friends and talk on MSN from time to time.

Now while all this is happening, Friend M and Friend O started seeing more and more of each other and both have develop feelings for each other as more than just friends. I didn't know this until later. At this time, I was developing feelings for Friend O, but I didn't know what to do with those feelings, so I just let them be. Friend M invited me to her house one day during the Christmas break, and out of niceneess, I invited Friend O along with me. While I was in the washroom, Friend M gave Friend O a letter saying that she wants him to be her boyfriend, and Friend O said yes. Again, all this I didn't know til later.

After a couple of weeks since that incident, Friend O announced that he was official with Friend M, and my initial reaction was to be jealous and avoided Friend O for a good while. I guess I just didn't realize my feelings for Friend O.

Then after a couple of weeks, I decided to act like everything was normal and that I can go on flirting and having fun with Friend O as he was perfectly fine with that. Things started to get more and more serious for me, and I was starting to realized that I was starting to have a real, serious crush on Friend O even though I know that he would never like me more than a friend and that he was with Friend M. And I know that it's wrong to flirt and like your friend's boyfriend, but I pushed that all away and went on as usual, flirting and leaning on him every time I get. Friend M was okay about all this as she knew that things would remain just friends between us.

Then summer came and I went on flirting and having fun with Friend O. I phoned him on a semi regular basis and even stayed up making his birthday present for him. He liked it of course. But...he knew that I liked him; he asked me and I told him precisely how I felt about him. We had a serious talk in which he asked me to stop treating him more than a friend and just act normal around him. He aslo asked me to forget all my feelings for him.

Now the problem that I have is...how do I act normal around him once school starts and to forget my feelings for him? Also, I don't want things to be weird and awkward between us, so I was wondering what I should do to minimize that.

Sorry for the long read and any suggestions/advice would be appreciated. Thanks!
