I am not sure what your life experiences have been in the area of relationships but the term romantic love is just used to distinguish it from say maternal love..parental love..the love a person has for a really dear best friend etc.
The capacity to experience romantic affections are Gods idea within human beings which has been marred by sin and the bible mentions about evil/deceitful desires.However liking someone in a romantic context can be cause by all kind of things like you have people who are infatuated by some singer they dont really know and have never even met..thats delusional as it's based on idolic fantasy.
Yet when you feel really attracted to someone in the right context such feelings are categorized as having romantic feelings for them..thats perfectly natural.
In terms of selling things off from that Is just the commercial element like valentines day..romantic environments ect...flower shops etc.
Saying you really like someone and they feel the same way too and saying you miss each other is all part of expressing romantic affections and for many they are real feelings and are genuine.Romantic moments are created between two people from so many things...a poem sent..a love heart sent,Holding hands,watching a summer sunset...the list is endless..
In terms of humans being unable to love only through God isnt exactly true..Humans have the capacity to give love and receive love even thought they have a sinful nature..Some people we know are just evil in terms of how they treat others for mans expression of love and Gods love are at complete different ends of the spectrum.Gods love is holy,righteous etc.. mans love is far from this...yet it still in many cases has certain elements of genuine care,tenderness,Sacrifice,affection and such like.
To " Feel" romantic love without a commitment to God
Is the exact same chemical response
As getting "high"
Dopamine is released in the brain
It is a temporal
Chemical ,albeit pleasant reaction
Which can not be prolonged
Hence 75% divorce rate, partner hopping, single mothers etc
Christians have the only source of true love
That is God
Surrender to God is surrender to his rules and examples of loving behavior
And the rules for said " True Love"
Are different, service oriented, fearless
And balanced and long lasting
Christians should not be slaves to
Emotions or The worlds idea of romance
We should serve only one source of
Love..and that is God
For God IS Love
