I'm also glad he texted you. I hate it that you're so stressed over this. It will only drive you insane trying to figure anyone out- including female friends. We are so complex- each and every one of us, that it would be impossible to understand the reasoning behind their actions. This is only your own mind and thoughts trying to grab for answers that have been built upon the foundation of your life experiences. His is much different from yours. My point is to try as best you can to stop dwelling. And believe you me, I know far too well about dwelling. Begin to only see him as a dear friend with no expectations. When you begin to change your perspective and the way you view the relationship you both share, happiness will surely follow.
Go with the flow of life. Enjoy him for who he is and accepting who he isn't.
It's not easy and will be difficult at first. But just try and see what happens.
I really must follow my own advice. Lol
