Genuine love means, that you just give. You might hope to receive something in return, but it's not required.
Of course, if someone literally only takes and never gives. you should stop loving them immediately. Too, that's unhealthy as well.
But genuine love doesn't expect immediate returns. It just is/
If I love someone, seeing them happy is all I need. I don't need anything more. Just seeing them be happy.
dysfuncitonal family, parenting (-), abuse
This is also a big problem in parenting.
Parents, often enough don't actually love their children. Because that'll threaten their authority.
So instead they manipulate their children to be happy about things, they aren't, to satisfy their need of control.
And then make themselves believe that'll be actual love. But it's just mutilating your child's soul, for your own happiness.
Which is actually abuse, not love. Quite the opposite
