I know how you feel .. I have a friend from grade school who I found on FB and it's like pulling teeth for her to talk to me .
She never e-mails me I always have to e-mail her if I want to talk and she always says she has to go , so I said then e-mail me when u can talk .. nope she doesn't ever e-mail me .

I have learned that on line friends come in your life one day and boom gone the next as if it never happened . It stinks how easy people can drop you without even giving you a reason , just makes you feel , like your not worth there time .
