I Miss Someone Very Much

I have mentioned this person before in my previous post. It's been more than a month than we haven't been close to each other. We don't really talk anymore and he doesn't seem to want anything to do with me. I miss him a whole lot. I also understand it was my fault that our relationship came to become like this. If only I had not opened up to him that much or I've pretended to be more positive, he perhaps would stay.
Through this time, I decided to calm myself down and told myself that he was just busy. After a few incidents, I guess he saw how things worsened for me. He was also there when my friends gathered around me to talk with me. After the talk, he texted me that he was glad that there are friends who care about me more than he does. It really hit home. He doesn't really care about me anymore, or, to be fair, not as much. It hurt so much as we had shared a lot. I don't know what to do. He was my best friend and the person who knows the most about me. It is very heartbreaking to know that he doesn't miss me as much as I miss him.
