<human>: Give me the gist of the text in a nutshell

I've never had any sort of realitonship with a girl, I have social anxiety and depression. Junior year a girl started talking to me, we really clicked and eventually got in a relationship. I broke up with her but we kept each other around.

It's senior year now I love this girl but I don't want her. She's the best thing that's ever happened to me, she turned my life around. She's giving me till the 15th to give her an answer. She's stayed with me hoping for another chance and because she loves me, but she's ready to get serious with someone.

I need her, I'm so attached to her and I don't know what do to do this just sucks. I do everything for her yet at the end of the day I'm the one who doesn't truly love her and want her and has basically conned her to stay with me all this time.
<bot>: I love this girl so much but don't want her yet I'm attached. I can't just let her ago, I don't know how to handle this situation
