<human>: A few weeks ago my girlfriend and I got into the same college, however she also got into her dream college. The rankings are not too far apart but it is pretty obvious that her dream college is more prestigious. After talking long and hard, she decided to come to the one I was going to. 

Of course, I would LOVE it if she comes to the same college as me. I love her dearly and because we are going to the same one, my mindset right now is to hold on for as long as possible... forever??? 

I never forced her to come with me, and she gave me a decent number of reasons why she decided this college that are not related to me. 

But damn, I feel so selfish. She could possibly be ruining her life. What scares me is that we have no idea what is going to happen on the other side. What if we change there? What if it restricts us from meeting new people? What if I feel obligated to always be an angel for her because she chose this for us?

What's surprising is that I'm not even a very good boyfriend. Sometimes I overreact, sometimes clingy, sometimes a little possessive, sometimes a giant asshole. The fact that she's willing to sacrifice that for me makes me love her even more.. but what will happen when it fades? 

Right now right here, I want to be with her for the rest of my life. Married, kids and what not (we always talk about this) but I'm not sure if my age and maturity will back this up in a few months or years.
 

TBH our relationship is not that strong at all, we fight all the time, little fights about big things, big fights about little things. We're young and stupid but maybe that's what creates our love? I know I repeated this a million times but I really want to be with her forever, but i want us to be happy. AND we known each other for our whole high school but we've only been dating for 4 months. 

And BTW we both submitted are SIR to the school so reading stuff about why we SHOULD'NT go to the same school won't be that easing for me ;(

Could you distill the essence of the text into 1-3 sentences?
