Asking internet people if someone is cheating, does that make you crazy?

This girl thinks that im having sex with my downstairs neighbor while seeing her. This all stems from and i quote “You wont delete the picture of you and her from your Myspace so you must be”

She went to Yahoo! Answer’s to ask if i was and now doesnt want to talk to me because of what the Yahoo! Answer people replied with lol.

Does this make her crazy?
