If I’m not mistaken, the view you are coming from is that relationship or love is all about giving and taking. To me though, love doesn’t mean you are entitled to any thing other than my reciprocated love.
Since you made reference of God, I am glad you did.
Remember this, God’s love towards us is the greatest example there is. He gave up his son to die for sinners and not for just the saved.
I guess that’s an example we need to follow. Don’t love for what you have to gain but for the pleasure you receive knowing that the person or persons in mention will be happy.
But don’t let love make you a fool.
