To be clear, you're not crazy. You're not stalking him/her or anything like that. Everyone has a friend or that ex-boyfriend/girlfriend they still check on in disconnected ways. You undeniably dabble in their life by checking their profile to get the latest update. Even though you may have their number you reject the idea of calling them. Because to be honest, you want them to make that first move. You want them to recognize that there hasn't been a conversation between you two for the longest time. You just want to be thought about.
I had scary thoughts that taunted me about my age increasing. It meant many of my clocks were running out of time. Being 28, single, with absolutely NO ONE on your radar was scary.
