How about I tell you that I don't love my mother.
Wait. What? You are serious? Is she dragging you down?
No never. I just don't love her
If she is not dragging you down then you should try and love her especially if she loves you back. As her child, you should appreciate your mother, the one and only person that you can trust and got your back.
I know that she loves me and I don't need to love her back.
Love is something that we feel with the heart, but if you can't feel it for her there is something wrong deep down. Maybe a therapist can help you figure it all out. This is an issue that shouldn't be pushed under the carpet.
