whatever his starshine may be,,but the most important thing is he is married! I hope i dont make u angry by saying this,,but please dont do this,,this will only lead to a lot of mess! He is married,,has a wife,,n probably kids as well. The wife n kids life will be shattered, as well as urs !Find a guy who will only b urs n no 1 elses,that way u will get a happier married life n wont harm any1!
Rest is upon u ! This was just my personal opinion,no offence on others who support such relations !
