This type of affair is one of two ways it may be experienced for those having an affair. Not every affair has limerence as a component.
This type of limerent affair is characterized by the betrayer believing they are "madly in love" with the affair partner, and they are willing to risk everything to be with their affair partner. With this type, betrayers feel love sickness when they are not with their affair partner and feel powerless to stop this love addiction to them. (Read earlier blog posts of limerence for a complete description of what they are experiencing.)
It is not uncommon for them to feel guilty about what they are doing, but at the same time, they feel they are no longer in love with their spouse and know that they will never be happy unless they are with their lover.
This limerent affair is not necessarily based on sex, but on the powerful emotions they experience with this person. In this type of affair, betrayers have most likely made the decision to leave their marriage. They believe that they can never be happy unless they get to be with the one they love.
Many times there is a pattern of the betrayer swinging back and forth between their marriage and their affair partner. When they are at home, trying to do what is right, they are miserable and feel they will never be happy. When they are with their affair partner, they are ecstatic, but may be feeling so guilty that they can't stand it, so they move back home only to feel miserable and to realize once again that they can never be happy unless they go back to the affair partner. The betrayer's in and out stance can continue for years. Betrayers often seem incapable of making a decision about what they are going to do. Even though they don’t want to be in the marriage.
This situation is not hopeless, even though you probably have been told numerous times it is by your spouse. While this description may cause you to believe your situation is hopeless, please know that it is not.
Often times with this type of affair, the betrayer has a very difficult time completely cutting of the affair partner even after the affair is "over." This may also be because the affair partner is also experiencing limerence.
Part of the process of working through this type of affair is the betrayer needs to understand what they are experiencing. They may continue to believe the affair partner is their soul mate, until they understand what limerence really is and how to get out of it. Until that is done this dance of insanity will probably continue for a long time.
