When I was at university, I had a group of six friends. We all lived together, partied together, chilled out all the time etc.
Sure, there were some I preferred over others. But we were one big group.
In the final year of university, one of the girls got a new boyfriend who I really really clashed with. As did others. He was a complete prick, and several other people have independently said the same. I remember him making one of the other girls cry. He was genuinely one of the nastiest people I have ever met. So I stood up to him.
Somehow all the hatred was then directed at me. And I found myself being excluded. We tried to make up, but I was never ever really included from thereon. The girl and the guy are now married.
Life goes on. I made new friends. I kept in touch with a few of them, and see them infrequently.
I recently saw a facebook photo of their reunion meal. After 6 years! I still felt a pang of hurt. Like I was 'wronged'.
