Love supposedly is not a feeling but sacrifice and it requires alot of sacrifice to maintain love.
I would like to establish a point if it's love then giving is required to enable this called love to be shown.

Love according to Gal 5v 22 , states love is a fruit of the spirit the process to make a fruit exist is by planting.

I would say first having know God as love , we need to understand every fruit is to be planted as a seed to give the required fruit.
So what then is the seed required for love to be planted and to be cultivated?
The spirit of God is the seed planted in a man to give the fruit of the spirit in itself has many other fruits but our focus is on love today.

This why I stand to the fact that people don't fall in love but grow in love.
A fruit don't fall from the sky but is planted, grows to become a fruit for those to eat from.
So LOVE grows from being planted and then blooms to become a fruit that is evident and shared amongst persons.

The process should be from planting before it falls.
I will leave you with this we don't fall in love, we grow in love.
