How do people fall in love?

Ever more I wonder how
other people fall in love.
How do they get someone to
fall in love with them? How do
they charm the ones they like and
attain the wished happy end?
What makes others inclined to
reciprocate in a true,
honest way offered feelings?
What does tug at their heartstrings
the most-most effectively
so they’d fall in love deeply,
without any trickery?
To me it’s a mystery
because I only know how
I happen to fall in love.
But it seems others don’t do
it the same way as I do.
In my case, it starts with
noticing someone with mirth
being interested in me,
wanting to spend time with me,
and just being close nearby,
but respect me being shy
and needing more time to warm
up to their affection, charm,
and kindness. I like when they
do not give up right away
but make the effort to keep
in touch and keep coming up
to me again and again.
I sure like it when the man
throws longing looks and cute smiles
my way, and possibly sighs.
I like when he carefully
and quite inconspicuously,
out of desire, tries to
touch me and then caress too.
And what really gets me is
randomly pulling me close,
thus showing that he wants me
his beloved girlfriend to be,
while holding my hand tightly
and looking passionately
deep into my unsure eyes.
Being wanted feels so nice.
And so, unawares, I fall
in, head over heels and all,
as I choose to give a chance
to the proposed sweet romance.
But every time I try to
do the very same things to
those I am interested in,
I never manage to win
their hearts over. Somehow it
never works on them one bit
like it does on me. Instead,
what makes me desperate and sad,
it rather just bothers them.
They reject me and condemn
for my attempted advance
without giving me a chance
to get to know each other
at least a little better,
like I would to any guy
who would all this on me try,
if he were law abiding,
polite and kind and charming.
I don’t understand what I
do wrong that it goes awry
always, every single time.
Why doesn’t it have the same
effect on everybody,
mainly if they’re already
looking for someone to love,
some tender and loyal dove?
Why is it so extremely
hard, even if he’s lonely,
to charm the special someone
whom my poor heart is set on?
Why does loving never work
to incite him to love back?
