Do I need to make things right with this person in my life? Even if I have tried and they have shot me down?!?

Along time ago I met this girl named Samantha and instantly I fell for her. Even tho she had a boyfriend we always hung out and even tho I have stayed over night wit her I have never done anything with her. Mainly because I feared her and was intimadated. I cared for her so much. After a while I grew jealous of her boyfriend and angry at myself for fearing to make a move so out of frustration I would end up hurting her feelings and we would be off of speaking terms. So last summer we became cool again and we had a lil get together with friends and she wS dancing and grinding all over me, things were great. A few days later I'm balling in her neighborhood when her boyfriend comes speeding into the neighborhood and almost hits me, he leans his head out the window and called me a ****** *****. I was so immature that I went down to her house slashed his tires and when he tried fighting me for it I kicked his ***. Few months later in January I contacted her and she told me she hated me and never wanted to speak to ne again. Now I hVe dreamed about her and mysf kissing and she told me she loved me. I have bettered my relationships with everyone in my life striving to be a better man, even with her mother and lite sister who hated me after that incident. Am I becoming a better man and is god telling me she is an important part of my life and future or am I just crazy and imagining things. Even after the things she said to me I feel like I deserved it and have since used it to better myself, I used to to it because I wanted her to like me even more than she did but now I am doing it for myself to have a better life and these things are falling into place and happening! Can any one help me?!
