Grow a pair and ask your wife is she is cheating on you. Tell her all the reasons you think she is having an affair and tell her you suspected one or more of the children were fathered by someone else. Say it to her face instead of slandering her to strangers. It's your marriage, you got yourself into it, you get yourself out of it or figure out how to fix it.


She will just deny it. It's naive to think that she will do anything else.
