Should I accept my cheating wife?

Before making any drastic decisions you should really try and figure out if its your baby or not. but it sounds like its not your baby...thats very strange that she wont show you medical papers. and the timing of her pregnancy is also off with the timing you guys had sex. I say, dont forgive her! you guys are married and she cheated. to me, cheating is absolutely unacceptable in marriage. thats wrong enough for boyfriends and girlfrends, but husbands and wives? absolutely not
