Ok he is cheating? What

You are cheated? Anywayzzz i have no right to interefere in your buisness. Ok i have one way of catching him...Just use netstat command on your Dos prompt and check whether the ID's are of same IP. Who knows if he's using multi-yahoo messenger. Or send him a spyware....if you can create one....I can't create it either but so dont ask me to.
