Emotional affairs can be very sticky. It can be very difficult to shake off if the partners in the affair have gotten very intimate. The resulting dangers will always be there.
Many people believe that there should be limits set in a marriage.
These friends can become too close.
The friendship, especially with the opposite sex, can become so intimate that it qualifies as an affair of the heart. It is usually defined as sharing intimate emotional details with someone of the opposite gender. It becomes more of an affair of the emotions if you keep this close bond with another person a secret from your spouse.
It can be damaging to a marriage. If your wife finds out about your special relationship with a woman, she might feel betrayed. She could believe that you violated a trust between the two of you.
It has not been established whether emotional affairs are purely emotional or if sexual or physical attraction gets into the picture. If one needs only to share intimate matters, why does it have to be with someone of the opposite sex? Why not share it with your wife or husband?
It could not be harmless, because it is difficult to reveal the relationship to the spouse. It could be just a tactic, of starting it as a seemingly platonic affair with the intention of making it sexual. Once it becomes a full-blown sexual/physical affair outside the marriage, the complications begin.
You may be deep in such an affair and want to break up. The first thing to do is be honest, tell your spouse or talk to a psychiatrist. If to share intimate details of your life is all you need, you could have talked to them at the start. Such relationships could mess up many lives and make you feel you should not have gotten involved in one of those emotional affairs.
