Doctor Answers (2) on Strange behaviour
It's necessary that you provide details about HOW this behavior of your friend is affecting you. You need to mention a little more about your relationship and the symptoms that your are going through.
From whatever you have shared here, your expectations are clearly different from what he is giving to your relation. And he is honest and upfront about it. So, I recommend you to stay away, if it's incompatible and uncomfortable to you.
