long story short I noticed it was a friend that had a crush on me a few years ago.. Anyways she's single and I'm single and I've known her for awhile now like 10-15 years..
This whole post is fishy and missing relevant info. You’re 28 years old and know her for 15 years? So that means you’ve been knowing each other since you’re 13.
If she had a crush on you and has known you this long don’t you think she would have made a move by now?
If someone who knows me out of the blue confronted on POF and FB I might be a little embarrassed too. Especially if I am not interested in him I would ignore the messages.
If you think you may have given her the wrong impression, only you know why that might be as we don’t know your history with her.
