Dear Prudence,
My mother and I have had a complicated relationship since I turned 14, her treatment of myself and others is erratic and unkind. Among her kicking me out at age 15, calling me abhorrent names, blackmailing me, and harassing those closest to me, I am at my wits end. I am now 22 and I have learnt that I cannot trust her. I discovered that she was cheating on her husband last October and sat on the knowledge. Her erratic behavior flared up again and she called me horrible names, implying those closest to me thought I was an awful person—I cut her off. She showed up at my door last week demanding we sort things out and claiming she’d acted that way due to her depression/BPD. This is a regular occurrence and never accompanies a genuine apology. I don’t want to sort things out and I am angry, it is a cycle I no longer want to be trapped in. I want to email her and tell her I know about her affair and ask her to no longer contact me. Is this too much?
