I had a situation like this before...
I randomly myspaced this hottie as i was bored between treating clients. Got chatting to her on the internet, she such an ace girl,, got some quality banter and genuine connection goin between us too. Was flirting away with her and i had the reigns of the convosation. She was working for my attention now. Asked for her number and BOOM! got it. Rang her....no response.
Week later i gave her some banter on her profile, to which she replies....
"Shhh Will! Give me your number btw, i cant believe i lost it "
Give it her again....text her....no f***ing response again. Was really confused about this tho. Just couldnt figure out why got blanked!??
