<human>: Can you provide a brief rundown of the text in within 3 sentences?

We [18] have been dating over 2 years and I am a very independent girl. As a result I've hurt my boyfriend by not being as involved in the relationship as he has. He is very emotional to begin with and because of my neglection he has closed himself off and won't let me back in. Soon we will both be going to university and college and it will become a long distance relationship (2 hours away.) Its not very far  but any distance in a unstable relationship is dangerous I think. 

What can I do to let him know I'm sorry for hurting him (I realized my mistake and I feel terrible. I never meant to hurt him he means the world to me.) I need to get him back to me but he feels I'll hurt him again.
<bot>: hurt my [18/F] emotional boyfriend [18/M] and need to fix it before the relationship becomes long distance and gets worse.
