Just part of the human condition IMHO.

Whats that ???

Why does my heart skip a crazy beat?

Sorry it's not more romantic, it's
chemicals & hormones.

(And when we don't know,
"Its aliens...its always aliens" )

Because we have a biological imperative to procreate.

I think we fall in love due to a mix of several different reasons: societal expectations, fear of being alone, the human need for affection and touch, processes in the brain are triggered that give us feel good chemicals (dopamine/endorphins/serotonin, hormones, the feeling of excitement love causes, the basic human need to feel wanted, procreation, and the inability for many of us to not learn from our past mistakes.

It always seems like a good idea at the time. Sometimes, it is. Other times, it's a disaster. Hard to tell which it's going to be at the beginning. But it's not something you decide, it's a feeling, and you can't really control those.

"Love"? What is it? I suppose the simplest expression is the one that appears to cross all the Ts and dot all the Is. Neuro chemical response to an external physical stimulus. We meet, our individual expressions and responses elicit such responses in each other that our desire to continue such stimulation with this one particular person becomes "addictive" or "compulsive" When these responses are no longer as stimulating as they had been, "Love" "dies".

Personally, I prefer the poetic explanation.

Love is an advanced stage of lust

Roses are red, violets are blue, love isn't real, everybody acts only in self interest.

Our hormones are bored and want to have something to do.

I think that people who fall in love make a conception about their own needs, and who the other person is, and then assume that the person they love is amazing, which will look after their emotional needs.

Because makes sex more valuable!

It's one of those gifts in this life.
