It is not unusual to lose the butterflies for someone once you notice that the person is returning your advances.
In this scenario, they are seemingly interested and now may want to pursue something with you.
As a result, you begin to feel less inclined.
You were so interested in this person initially.
There is something about human nature that makes us curious and so excited about someone when they aren’t showing us as much interest.
We are mystified by this person.
You start thinking about what this person is like because you barely know them.
You start wondering if you even have a chance.
Those types of feelings get you excited as a human being. The sense of uncertainty and wonder.
Once this person starts showing you the affection that you may have thought you wanted from them, that air of mystery about this person starts to wane.
They are no longer the unknown.
They start becoming the known.
There is something very predictable and boring about the known.
You have seen it before.
You have had that person in your past who gushed over you and gave you a lot of attention.
You have had that person in the past who believed that you could do no wrong.
Now, this person that you have liked is showing the same traits.
This is familiar to you and all of a sudden, this person who seemed so mysterious and different becomes like many of the rest.
The experience is no longer new, it is familiar and somewhat uninteresting.
You want to be kept on your toes with excitement.
You want to be constantly wondering if you have a chance or whether this person even noticed you when you looked their way.
With that sense of danger and uncertainty gone, now replaced with someone who is returning the same emotion your way, you become critical of them because they are just like everyone else.
It becomes mundane.
The mystery is essentially gone and hence the emotion.
You no longer feel that urge to get to know them because you can now put their story together in your head based on the evidence that they have presented to you.
It’s almost like the secret is now out and as a result, there is a lot less desire.
