<human>: I've been going out with this girl for a year and a half now and I really care about her a lot. But we are two very different people and things just aren't working out now. She's already brought up the idea of marriage and I am not exactly keen on committing myself at this point in my life. I feel like she is holding me back from enjoying my youth. 

We had a "break" a month ago and I felt great about it. But she couldn't handle being without me and begged me to go back to her. Me being me, I ended the "break" but I feel like I am only dating her now out of pity and nothing else. 

She is also very emotional and I don't want to hurt her. 

I've been advised by family and friends to just end it already but we have exams right now so I want to end it at the end of that so she doesn't have unnecessary distractions. 

Also we have a lot of mutual friends so I really want to break it off nicely without too much heart break.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Want to break up with emotional girlfriend. Waiting until after exams to do so. Not sure how to do it without hurting her feelings too much.
