text: can a person start dating after legal separation or does he/she have to wait for divorce? once a couple are legally seperated, can they start dating other people or is it best to wait until the divorce is final? could one spose use it against the other during the divorce if the other started dating?  for instance, man and woman seperate, man starts dating this girl he's been friends with for years. when the divorce is filed, could the woman use this against the man? ha ha, aww, how sweet. people have sex with other people during marriage! of course you can date- whenever you want. if people can do crap like that during marriage, there is nobody gonna stop them during a separation.
