No, you don't have the right to call first thing in the morning, at a time when you KNOW I won't answer the phone, leave an angry message, and then demand that I call you on MY birthday. This was my day to spend how I wanted which I did, and it didn't involve dealing with you because I didn't want to. No, the world doesn't revolve around you. And, yes, I know you probably want me to call you before you leave the COUNTRY next week, except you didn't bother to tell me that when I did talk to you less than a month ago. As painful as it is, I'm making the right decision in not engaging with you right now.

Yes, "no longer interested" means what it says. You can't be that desperate.
Everyone is "desperate for" people until I show up.
