<human>: I have known her since high school and we are in college now. We started dating last year In May because we hung out so often that we developed feelings for each other. It has been 10 months and sadly I just don't think I feel the same way I did before after all this time. She is my best friend and she comes from a rather broken home; her mom is clinically depressed and her father has anger management issues and sometimes verbally abuses her (never physically). She constantly tells me about her home problems, how she feels like falling apart all the time and wants to hurt herself or hit something and every time she texts me it gets worse and I just can't deal with it anymore. I tell her that it makes me angry to hear this, and in turn makes her feel worse that I feel bad. I can only do so much for her, I tell her joining the Air Force or Navy would be a better option than suffering at home (her father was in the Navy and is used to moving a lot).

She doesn't have a whole lot of friends and I'm probably the main person in her life who is there to support her. These last few months we have argued several times and she has noticed that I am losing interest, fast. Every time the subject arises she sends me about 100 texts saying how sad this makes her and how depressed she would be if we broke up, but I feel there is no point in going out anymore. She's the sweetest person to me and I love her so much as a friend but that feeling just isn't there anymore and it's unfair to her and I that I can't truly return her affections... I feel so guilty about it because I know what it feels like to be in love with someone who doesn't feel the same plus she has a ton of other issues and i will just be adding to it. I just don't know how to break it to her...some encouragement and advice would be greatly appreciated.

Can you condense the text into a few key points?
<bot>: I am dating my best friend but after 10 months I don't feel romantically inclined enough to stay together and need a way to tell her. And also some encouragement because I feel horribly guilty.
