Infatuation for the most part is our own "projection" of perfection we see in someone else without having spent much time getting to know them. Both people tend to bend over backwards to present their best foot in order to impress the object of their affection. They make each other's happiness their top priority!
In fact most (new relationships) have an "infatuation phase" where laughter and long conversations come easily, the word "no' is seldom if ever used, everything you want to do he/she is game for doing, cards and token gifts are given "just because" and oftentimes sexual chemistry is off the charts!
It's no wonder that anyone with limited life/relationship experience could easily believe they have found their "soul-mate" the first three months of any new relationship.
True love can only come after one really knows the "authentic person" and not the one they presented to impress you early on.
You now have had some major disagreements, learned about each other's "deal breakers" and boundaries along with the "baggage" they carry around. Nevertheless even with their imperfections (you still feel at home) with them. That's love!
