Don't know what to do..

2 Days ago I made a promise to this guy that he won't lose me to any other guy until he's ready to be in another relationship. Then unexpectedly the guy I hadn't talked to in over 10 days decided to text me. I wasn't even thinking about him before friday because I didn't wanna be sad and mad. I used to think about this quote "I'm glad I had the chance to meet him, but now I'm glad I can move on and forget him. I wish it didn't have to end this way, but he's  damaging my heart, which is not ok." I don't know if he heard me that day or not but when I said "this guy told me this last year and I haven't really listened to it and I think I should. He said It's what you want not what they want" weird thing is I still am not listening to that. I still am listening to what my friends say. I try following my heart but I feel like my heart takes me in the wrong direction because I always get hurt when I follow it. I can honestly say my friend was right about me caring to much about people who don't deserve it. She also was right when she said if he couldn't listen to me then that's a sign he's just not worth it. When she was with me over the summer and my relationship was on the verge of ending I did anything I could possibly do to fix it and make it better. We were 7 blocks from his house and I knew I needed to get there to straighten things out so I ran the entire way because I did not want to lose him. I was a wreck for 7 months and then he brightened my day and made me happy again. Even when people told me he cheated on me I listened to his explanation and made things work. I gave him chances because I wanted the relationship to last and not break. I knew that if it broke I would be a wreck again. Then the day he called me and said "I love you" I was really happy. When you love someone truly you will go out of your way and further than your limit to make things work. Even though my friends say I deserve better and he is just an ass, I still love him. That is one thing that won't change. I get he can be mean and not caring at times, but that is just him. I don't want him to change for me or for anyone. I fell for him because he is himself and not what others want him to be. My friends don't get that this is how he has always been. If you excepted him in the summer why don't you now? He is the same person he was then that he is now. He has always been the same person. I don't want him to change because I fell for the guy he is now not who he would be if he changed. You can say I'm sticking up for him I honestly don't care. You saw how happy I was in July and how I acted when he would talk to me, so you can't say he didn't make me happy. At times yeah he made me mad and upset, but all relationships even marriage you have fights. It's no different. So why talk about my relationship. I can honestly say if he cheated he cheated, but my heart tells me he didn't. If he did you think I would have stayed with him for 7 weeks no I would have broken up with him that same day. I am running after him because I love him. If you can't understand that then I don't know how to make you understand how I feel and what I want. There is so much that went on this summer and so many feelings. He acts like he doesn't care, but do you know that for sure?? Did you ask him?? No, so how do you know he doesn't care. My life will be lived the way I want. Everyone gets hurt at least once and there are always heartbreaks, tears, memories but that doesn't stop you from going after what you want. I take the time to express myself. Yea I know he doesn't deserve to talk to me and why should I listen to him when he wouldn't listen to me. I don't know I really don't all I know is you go after what you want and who you love. Even though I made a promise to my new guy friend because my ex won't get me back. I just want answers and I want to know how he feel or what he feels. That is all I am looking for. The guy I made the promise to is sweet and I'm beginning to like him. No matter what my ex will always be in my heart because there will always be a part of me that still loves him and he knows it.
