Greg Grant. Stood 5-5, didn't even start for his hs team until his senior, nor varsity until his junior year, got no d-1 offers, and still made the nba (despite a tough home life).

Can I recommend Introducing Cognitive behavioral Therapy if you are suffering severe depression. Fiction reading can help, but only so much, practical steps help more.
I completely understand, that's extraordinarily optimistic and romantic and by all means ideal, but I dont think it's very realistic unless he's really working at it. Like addiction, this kind of stuff isnt "cured", it may go into remission for a while but it takes an active effort. To answer a question from another post, no one fixes it, there's no "fixed".
You sound like a smart, articulate, obviously dedicated girl. Dont lose sight of the fact that YOU have potential to be realized too, and the path to those dreams will be easier with someone who is capable of being more supportive, and not abusive. If you get a chance, pick up a copy of a book called "Love is a Choice", it's a little Christian-y, but I think it would couple with your situation very well. This relationship is just as much about your fear of regret as it is about his abuse, they're codependent. You, are codependent.
