This question supports my point and validates MJB's suspicions on the matter. If these relationships are used to foster a plan B then your marriage is a failure waiting to happen. Further, those type of relationships tend to serve as compensation for whats lacking at home. And as a result they are easily turned into something more harmful in the event things begin to go south at home. Instead of working on things at the homefront, you tend to use that friend as a shoulder to cry on, ear to whisper in, and that will soon turn into a pussy to fuck or dick to suck.
But to answer your question... Turn to for what?? Why would i need someone to turn to as a grown man of means? I would collect my thoughts and emotions and go on with life.
