One thing I often saw in practice was when someone met a potential partner and was certain he/she was the one. They were about to drop everything, including their spouse, because this felt so right. How could it possibly be wrong? They had such a good time together. He/she was my lost other half. Often this was due to compatibility in bed. Of course, this never worked out and the craziness of both people would soon emerge. When we meet someone we are in the midst of romance which may mean some compatibility, but often it means good fun and sex partners. Living together takes the blush off the rose. This rush of love is wonderful but we should be wary of it. And as always, listen to Karen.
