<human>: Can you give me a shortened version of the text?

This is my first boyfriend. He's an absolute sweetheart and I like him a lot as a person. He's very serious about our relationship. He loves me to death, but lately I haven't quite been feeling the same way. We have drastically different personalities and I don't connect to him on an emotional level. Lately when we've been going out it makes me uncomfortable when he touches me or kisses me. We've been dating for nine months but I feel like he still doesn't know me very well. This makes me irritable and critical of him sometimes, and he doesn't deserve someone who treats him that way. I think I want to break up with him. But it would absolutely crush his heart. 

He's leaving for college soon and wants to maintain our relationship but I'm uncertain about that too. I feel bad, because he didn't do anything wrong, he's just a tad naive and we don't really relate. I'm not sure how to articulate that. I've never broken up with anyone before and don't know how to do it with minimal emotional damage. pls advise. 

I'm hesitant because I do still care about him but I'm not sure if I care about him on a romantic level. It would tear me apart to hurt him. But I guess that's how all break ups go.

Or should I give this long distance thing a chance like he wants? ahh idk.
<bot>: I'm pretty sure I should break up with my first boyfriend, but it would kill me inside to hurt him. I'm inexperienced. What do I do and how do I do it?
