<human>: Can you summarize the given text in a few sentences?

I am an 18 year old male in community college and this has affected more than just my relationships. This problem comes from the fact that I don't drink or smoke and I don't like parties. For most of my relationships this wasn't a problem because my girlfriend didn't do any of that stuff either. But with my last girlfriend it was a problem, and it evetually led to her dumping me. 
 
We started dating during senior year, and up until the end of the summer there weren't any problems. We didn't need to drink, smoke, or party to have fun, so we didn't. I found out that she had drinken a little when she was a freshman and even that bothered me, despite it being so far in the past. After summer she went to a college that was a few hours away and I stayed home. As soon as she got to college she started partying, started to drink a little bit, and joined a sorority. Everytime she told me about a night of partying I felt sick to my stomach. I hated hearing about it but at the same time I was jealous that she was having so much fun. This led to communication problems and she decided to break it off. 

I don't know why her doing that stuff makes me so uncomfortable but it does, and I hate myself for it. I feel immature and stupid for not accepting what she does and for not doing some of it myself. I was uncomfortable when some of my friends started to do it as well. I want to stay sober but now that I am in college I see that finding someone who has the same stance on these things as me is going to be near impossible. I don't know what to do and I am so upset because of it.

Thanks for reading, I would appreciate any help at all.
<bot>: I don't drink, smoke, or party, but SO did. Made me uncomfortable and led to her dumping me. Hate myself for my own views and don't know what to do.
