Husband's friend has some ulterior motive in wanting to break up this marriage or he would have kept his lying piehole shut. The M-I-L must not have much interest in this couple staying together either, or she would have told 'husband' the truth of the matter instead of refusing to tell him what happened. The husband likes or trusts his friend's word over his wife's word. This marriage is in trouble, either over this incident or a future problem. Has this particular friend got anything against wife to cause him to tell this lie? Because it sounds like he has been doing this to break up this married couple. Is the friend married? Maybe he gets 'lonely' when his buddy spends his time with his wife instead of him. This might be enough of a problem for friend to cause him to make up lies to tell. Wife would be well advised to lose all three of these people if her husband leaves her due to his friend's lie. (husband, friend & friend's M-I-L) Just get as far as possible from all three of them & not have anything further to do with them! Let them have their little lying circle jerk without having her to pick on.
