This is first time i have heard story so similar to mine, of truly no bonding between mother and daughter. Like finding out about cancer surgery only at last minute. To me, that is a clear sign we are not a part of their lives. My mother pulled similar trick.

My mother also had better relationship with my cousin than with me.

I dont know why i was left out. They tried to pretend it was not true. That was even more confusing. They gave me ugly name too!

She did not take care of you when you were young. You are not together now. If i were you, i would not worry about that future. She will not want to be with you. You will have no obligation. I had none.
