I totally agree with @burning spear...when it comes to house helps husbands should keep off that department, your wife should be in charge. If the house girl says she was touched, asked to undress and your wife informs you about it, then deal with it via your wife...I really don't understand what angered you so much to want to confront the doc at 10pm, if anything it would have caused more problems....cut your wife some slack, I believe she can handle that issue stop being overly domineering...
Problems can get out of proportion, and not only in the wee small hours. Don't let the problems eclipse the Master. Let the Master eclipse the problems.
