It's scary; not your typical Webster's definition of the term but more or less a synonym of fear.
Falling in love; knowing that you're devoted to making another human being happy and what they make you feel is identical, it's clear.
It isn't always good. Sometimes it doesn't work out according to the blueprints, there's bumps in the road, but you choose to remain in that lane.
But it also isn't always necessarily bad. There's a sense of satisfaction in knowing you're the source of someone else's joy, helping relieve at least some of their pain.
Honestly though, who can tell you for a fact that they don't experience emotions? No one.
It's just a matter of picking the right person to sit through the highs and the lows, the fights and the woes that are directly related to being in love with someone.
