I don't understand this psychology.

It is like that with most people, you got to find a balance

You have to understand not to give them everything. You give them some... they take... you stop giving them... they want... they give... you take... in reward you give... they take... you stop giving... they want more... thats how it works

Remove expectations while giving and feel the magic in the process.

It is not love, they are narcissists who only pretend to love in order to get what they want. When they have worn you down or used up whatever you have to give they are gone like a fart in the wind...

Gimme gimme gimme

Survival of the fittest maybe..🤔

Selfless thinking

Cut them off and pretend they don't exist. Live happily.
