my long lost best friend

Today started out terrible to be quite honest. I woke up feeling upset from the night before. I had sworn I would be done with you. You left the worst taste in my mouth and I had had enough. But of course he infected my dreams, and I woke up feeling nostalgic and missing him more than ever. I kind of brushed it off and tried to move on with my day, but it was apparent that the day was going to suck. I didn't feel productive at all. Then out of nowhere I received a text from him. My heart could not stop racing, I hesitated to say anything back, but I caved. We started to talk, and ironically we have more in common. We are both in a rut in our lives and just looking for happiness. I asked him to hang and to my surprise he said yes. We just drove around and talked about what we felt and to be totally honest, I have never been that comfortable before. I talked to him like a real friend, I wasn't scared to say anything or tell him anything and it was nice. He asked me if it was okay if we were friends, and I told him that that is all I have ever wanted. So long story short, he and I decided to be friends and not strangers. To hang out and be close and talk. He told me that he doesn't find me texting him all the time clingy. It makes me scared though, because I know how he has been in the past, but he seems like he wants to change so bad. He regrets being an asshole and says that now that is how everyone views him. I'm honestly stupid for letting him back in and thinking that anything will change, but I still need him in my life, and if he makes an effort, then so will I. But if this turns out to be like all the other times before, I really will need to make up my mind about how much he truly means. God, I am such a sucker, but I still have faith in this kid, and if he is now gonna be a real friend, I am not about to give that up. I still need you.
