<human>: Condense the text into a few key points

When I was 15 I met the love of my life. After a failed engagement, 8 seemingly endless years of back and forth, long-distance and heartbreak, he is back in my life. We've been spending a lot of time together lately and there has been affection. He is the one that I never got over and every time he comes back around, I fall in love all over again. I brought it up to him, and he said that I didn't want him because he is broken and I would end up hurt (not in those words). I don't know what to do. He is not my family's favorite person and vise versa. The last time he and I tried to make things work, he was leaving for a remote place for a year and I was unknowingly going through a severe depression, I ended up cheating. I have since sought treatment and am confident that I can be a loyal and trusted SO and friend.
<bot>: Longterm on-again-off-again is potentially back in my life and for sure back into my heart.. don't know where to go from here.
