<human>: It's been a month and a half since he [17M] broke up our 2 year relationship because I[17F] was a terrible girlfriend. Mentally abusive, but we still loved each other through it. I've been struggling with depression for a year, which was the beginning of the downhill fall of our relationship. 
I realized the error of my ways not long after we broke up after taking an aerial view of the relationship, and I apologized profusely about two weeks ago. We see each other and talk, have been trying to be friends. 
Today I apologized again and professed my love for him. It's true. I never want to look at anyone else in my entire life, and now I know what I was doing wrong so I can do it right again. I told him that. I told him all I want to do is make him happy, which is completely true. He said he didn't want to get back together, got up, patted me on the head, and walked away. 
I don't know what to do. I can't make him come back, but I love him. All I think about is him, and how I had all I will ever need in my hands and I ruined it. Like the scene in Tommy Boy with the roll. 
I have so many feelings that I have no use for.

Help.
