Sadly your “wants” don’t match what’s going on. If you didn’t have normal relaxed relationship for 13 years there is zero chance that you will ever have it with this man. No that’s not how friendship looks. You are unable to express what you feel and if you do he punishes you by ignoring you. That’s not how friendships work. And it’s sad you think that his behavior indicate caring for you. That’s not how caring looks.

On the 06/29 after ten days of not seeing you he wrote (didn’t even call) that he can’t see you and today is 07/06 and you still haven’t seen him. 17 days and counting. Prior to that you’ve never see him alone, it’s always just waking on the street. Had he even call you since 06/29? I am not sure how you can call this romantic relationship or friendship. Sadly it’s none of that

You can’t change other people. You can’t make him into someone he isn’t. Hoping otherwise causing you unnecessary suffering
