I think you have to get through that faze of infatuation, and if the relationship survives, then you can create a healthy, loving relationship. Let's say a client, someone in their mid-forties, came to you and said that they were infatuated with someone. Well, I'd feel a mixture of joy and sadness for them, because it's great, but there's also pain involved. Infatuation encompasses fear and anxiety and tension and stress, all the negative emotions that come with that hormonal rush of infatuation, along with the joy and pleasure of loving someone. There's nothing wrong with pleasure.
Pleasure is good.
But that's very different from having a committed relationship,which takes skill and maturity. Because of your work, I'm sure you hear a lot about conflicts within relationships. Conflict can be an intimate experience, and it can be healthy, or it can be unhealthy. I've known couples whose only source of intimacy was fighting with one another for their entire 50 years of marriage. When it comes to anger, healthy couples do things differently than unhealthy couples, or couples that don't last long in a relationship.
