Because she's selfish and wants you and the other guy.
My ex cheated on her new guy(with me),two weeks into the relationship with him.
While she was telling me there was no one else.
So we hooked up,in person it was like "I don't know if I love you now,but I really did"
I was like... this is very weird... who says that... and does these things... if they don't have feelings...
I put the puzzle together
sure enough on myspace 'in a relationship'
= huge confrontation.. lol.
If she has a social network site... check it.
