"I love you."

"At what cost?"

Is the fear if you're growing up with the idea that love is always transactional. 

Thus, you will never understands how it does feel to be loved.

Because the comfort is material,

The empathy is bills,

And the care is paid,

It seems everything comes at a cost, like love is a currency. 

The amount of love given is treated as an investment for the returns that expected to be higher.

And you never understands the feeling of crave for love as you have died to filled the account.

That's where the fear are coming from, because you are prolonged to have nothing in your pocket. 

You have given so much 

So much that you have ran out of it.

The currency haunted your mind until it grows out your poverty over love.

The fear of loving closed out the door because you are afraid to give more than you can do.

As you are now poor and have nothing but the emptiness in yours.

Actually, you shouldn't have to be worry.

You will later understand how love supposed to make you feel rich.

Because it is actually given for free, and there is no currency bounded to make you received more than you ever should.

And you are so much worth to be wealthy because of love, not get starving because of it.
