Dating expectations too high
When partners place at least some responsibility for the success of the relationship on themselves, Lowe tells Web MD they ultimately will get more from each other.There is perhaps nothing quite as exhilarating as the heady feeling of falling deeply, madly, passionately in love.
They become very concerned if the other person doesn't call them quickly or doesn't want to see them with increasing frequency," says Jo Ann White, a relationship expert and psychology instructor at Temple University in Philadelphia. Many times, she says, one partner simply doesn't want to move that fast.
While some call the magic "limerence" -- that almost mystical connection of body, mind and spirit -- others say it's simply the most powerful sexual chemistry they ever experienced.
Regardless of how you define it, experts say once we do experience the "high" it becomes etched in our brain.
"Some people, particularly those who rush into marriage, have this idea that they are going to be madly in love with their partner 24/7. Research shows that at least part of that initial "WOW" feeling we get with our partners may have more to do with fluctuations in brain chemistry than flutters of the heart.
They firmly believe that not only is it going to always be this way, but that it always be this way," says Lowe. "When a man and woman fall for each other, it is in our biological best interest to become a little bit obsessed with each other.
Indeed, experts say that when a natural sense of entitlement doesn't rise up and come to the surface of a love affair, it won't last -- no matter how hot the passion.
