<human>: I know I'm young but hear me out if you please. (:

I've been in an open relationship with this guy for a year, and the age gap raised eyebrows at first but when everyone saw it was loving they backed down. 

Fast forward to now and I want to move on, but my reasons don't feel good. 

He's the sweetest and kindest guy ever, but we have very different opinions, ideas and passions. I'm super ambitious while he isn't, and he gets emotional and upset really easily. I feel like I spend more time fixing arguments than enjoying the relationship...

Problem is I do love him, and the thought of him being sad cuz I left him absolutely crushes my soul, makes me cry. He says I'm the only good thing in his life... I hate that responsibility... I feel like I can't chase my dreams because I have this burden to carry... I feel like a total selfish bitch. 

I'm currently in hospital so I've finally for the first time had an excuse to be alone with time to think about us. I don't know how to do it in a way that doesn't destroy him and our friendship. I can't figure it out.

Condense the text into a few key points
<bot>: Want to break up with a guy who says I'm the only good thing in his life. The guilt of breaking up with him kills me. I feel trapped and don't know what to do.
