<human>: When I broke up with my ex, it was amicable and we stayed friends for a year after. It got too difficult for me to see him moving on, so we stopped being friends. I don't think there were hard feelings, just a lot of termoil. 

Anyway, my problem is this:of my friends even said 'we're not going to stop being friends with him just because you've broken up'. OK, that's fair enough - it does hurt my feelings because I was going through a hard time, and it felt like the people who were supposed to be on my side weren't. 

The thing that bothers me is that none of his friends wanted to stay friends with me. It's made me feel, for the past 7 years, that I'm not good enough as a person. Even during our time together, his friends didn't seem to like me as much as I liked them. I wanted them to like me, I didn't try too hard, but I was just myself - maybe a bit shy. We all had some great times together, but now, they won't even be facebook friends. This is really raw for me because I keep seeing facebook updates about how happy they all are. This just makes me even more depressed: I'm unhappy. 

His friends love his new girlfriend and they're all a group of really close friends. It's all trashed my confidence and I don't beleive that anyone will want to be friends with me, not even my own friends were on my side. 

No one likes me and I don't know how to live like that. I used to be happy-go-lucky, funny, and confident. Now I'm a shy recluse. What should I do? I'm pining for a group of people that don't even think about me anymore.

Can you summarize the given text in a few sentences?
<bot>: Why did my friends and my ex-boyfriend's friends choose him, and not me, even though me and my ex didn't fall out. Why didn't he stick up for me?
