Should I Give Up?

I had my guard up. For about a year. Then I saw him and I felt something inside, I can’t explain it. It took some time to get close enough to him. But I never felt like I was doing it for me. Something just said that he needed me there. I didn’t give up, even when everyone said I should have. Even when he said he didn’t need me. I figured him out quickly. I don’t think anyone else has ever been able to. And he told me not to fall, it’d be hard not to, but don’t do it. And I don’t know if I ever fell, but I cared. I saw myself in him. He was dealing with things that I’ve already been through. So I understood. He got scared. He didn’t want someone to take care of him. I can understand that. But it’s so hard to watch someone destroy themselves. I tried to reach out, but it was like the harder I tried, the more he pushed me away. Then when I cut back he would beg for me to come over. I couldn’t play that game. I couldn’t act like I didn’t care. And he didn’t have time to care about anyone but himself. I tried not to be upset. I’m not upset because he doesn’t want me, it’s because he does want me and need me, but can’t stand the thought of being hurt again. Why am I drawn to this? Why do I feel like I still shouldn’t give up on him, no matter how much he has hurt me?
