1) Is it possible that gaslighting and narcissistic behaviours can be done out of love?

2) Why do parents behave as such?

3) Does anyone feel obligated to support your N-parent(s) after moving out due to guilt or moral obligations?

I'm asking because I personally struggle with these questions and would like some perspectives. For me, my mother is pretty much the typical N-parent throughout my entire life, but she has given me a huge down payment towards an apartment so that I could move out (like 80k). I despise living at home but now I feel obligated to support her financially as she approaches the age of retirement. Maybe this is another guilt tactic? So how would you react to these conditions?
