Dear Daughter • OK. Short answer first. Yes. You really can. Breaking off contact with your mother is certainly within the realm of possibility. People break off contact with other people all the time.
It’s a good thing when family members can work together through their issues. That can only happen if everyone a) acknowledges there’s a problem and b) wants to own his or her role in the problem. Let me also make it very, VERY clear that there are relationships that absolutely should be terminated. A friend of mine who was sexually abused throughout her childhood by her father has no contact with him now — nor, in my opinion, should she.
