I Have Lost a Friend

What Did I Do?... I didn't know her and yet we lived in the same building and went to the same college. We're even in the same major. Talk about coincidences. It was my third term, and I met this guy in class. He was very nice for someone I just knew. He talks a lot for a guy. And too helpfull. He was always offering to drive and picking me up to college. Now, he was so nice and it didn't hurt to receive a little kindness once in a while. We started going out, not a date, just friendly hang out. But then I learned he have a girlfriend in the other class. Honestly, I didn't feel any attraction towards him, I mean he was a really good friend and that's all. But that didn't justify him giving me the wrong vibe, acting like he was single and way too nice just to be a casual friend. I felt like a mistress! I let it go though, and it was all good again. He sometimes confided about his rocky relationship with his gf. I responded like a good friend, giving him advice here and there to keep his relationship.Long story short, I got to know her girlfriend because I didn't want her to feel like I have 'something' with him. We kept our friendship as transparent as possible to her gf, to the point that I started to hangout with this couple together. So it was safe to say that I became a good friend with both of them.This was when all things started to fall apart. I knew that he had been lying to her all this time, and he didn't feel guilty at all. I knew that he flirted with other girls. Though I never ratted him out, I grew distant to him and start to got closer to his gf. We studied for exam until midnight together, had sleepover, share foods, she stopped by my apartment a lot and vice versa (we live in the same building remember?). And she also confided to me about her relationship with him. They both trusted me. And I didn't know what to do, so I never told her the truth about him.It was the end of third term and we had two months holiday. I went back to my hometown because I was kinda homesick at the moment. We rarely kept in touch when I'm at my hometown, I didn't really chat that much.When I'm back again, suddenly she and him just grew distant and different. I'm not exaggerating. They just changed. I don't know what happen. They didn't seem excited when we hang. He suddenly grew quiet when I knew he liked to talk. At first I didn't really notice the change, but as days passed it was getting worse and very prominent. What really hurt is that they acted like nothing was wrong and faked their way through conversation. It was pretty clear they were getting uncomfortable around me.What is worse than losing friendship? Having a fake friendship. So I stopped hanging out with them, tired of being the only one who tried to make this friendship works. I never confront them for the real reason why they doing this to me. Maybe she found out that I used to go with her bf behind her back, she got mad with him and he got mad with me...Up until now, I still don't know the reason why we are not friend anymore. And maybe, I don't want to know why.
