Distressed friend, need help.

Dont b sorry! I am not..I believe I got my revenge by not letting it affect my life..u know whats the weirdest part..some people do all this BS just to ruin lives not for the sake of sx..they can easily get sx from a call girl or in this case his wife but some people enjoy ruining lives..y satisfy them?
As I said earlier sometimes its good to b selfish..lets say even if I did warn everyone about him whats the guarantee they wouldnt judge me they wouldnt talk behind my back wouldnt blame me..would they have allowed their sons to marry me? Heck no! Y do them the favor when they wouldnt do the same! Humanity is a sin here in pak! If this would have happened in the west im sure the best solution would have been to report him to the police so he wouldnt ruin more lives but thats not the case here..everyone on his own..
If the victim thinks it would help her in any way if she told her parents then she should..let her decide on her own
