U really don't know the truth do u?

Even if u go to court what would u say, he is married to another woman! that's not a crime and if u say they r fooling around (not married) then u need 4 witness that saw them in act.

My suggestion: Ignore the whole subject, try to take care of ur husband more than before, u r the only looser if he decides to leave u for her, try to keep ur home by providing extra care and not by revenge.

Think rational and don't act on the basis of ur heart feelings.

Good Luck

note. most men are like that, u won't find any better
