<human>: Can you condense the text into a few key points?

Please do not make any judgements based on our age. Bullcrap about there being plenty of fish in the sea or how I have my whole life ahead of me will not be helpful.

So we've been together over 2 years, which is a lot for a high school relationship. But the last half of it has been very stressful. She is way too obedient and supportive of her emotionally abusive mother, puts me extremely low on her priority list, tosses me aside for anything else that comes up, is very inconsiderate of my feelings, forces me to make all the sacrifices, and the list goes on...

At one point a couple months ago, I had thoughts of breaking up with her, but right before I did I realized the reality of how hard things would be without her. Because despite all the flaws, she's a great person and I really love her.

Basically things have gotten so bad that I feel the only logical solution is to end it. I don't like the person that she has become (things weren't always this bad), and I shouldn't try to change her. But the problem is, I'm so attached to her that I can't imagine being alone. I know it sounds overdramatic, especially being only 17, but the feelings are very strong. I don't want to throw away the last 2 years and just end it, and I don't want to be single or with anyone else.
<bot>: My girlfriend has changed over the past 2 years and is no longer the type of person that i want to be with, but at the same time the last thing I want to do is end it.
