So years ago I worked with this girl and I was crazy about her and she knew it and she rejected me when I asked her to be my girlfriend. I wrote her after that summer a lovely letter and never heard from her. So three years later I saw her on fb and friend requested her, she accepted. she is married with a kid. I congratulated her and made small talk, then a day later she unfriended me, then I friended her again-she accepted and then more small talk we had she sounded happy to hear from me asked how I was doing, etc. then she unfriended me again just like that, not only did she unfriend me but she blocked me so I can't even find her even through mutual friends. but I know she still has an account why is she doing this?
