Hi there,
My ‘home board’ is Coping and Healing from a Parent/Family Member, but I went to the Staying board just now to ask you for some advice about relationships because the ‘fleas’ I picked up are doing no good to my relationship with my partner.
In a nutshell: my mother has uBPD. I have been NC for a year. She abused me sexually, emotionally and physically. I have PTSD and I have trouble regulating anger. In many ways, I respond like a pwBPD when I am angry. The emotion rises quickly and sometimes I shout at my partner (who is one of the few people with whom I feel safe enough to show my feelings). Of course, he does not deserve to be treated like this. It makes him very sad and upset.
I have had a relationship with my partner for two and a half years. My MIL has BPD traits that are very triggering to me. For instance, she makes mean remarks and bullies me when I am ill, and afterwards she denies or ignores her own behaviour. (There is a whole lot more but I will try to keep it short ) Her remarks spark my anger, yet I am too afraid to ask her to stop (asserting myself has led to heated discussions more than once and I really do not like having words with her). After visiting or answering a phone call from my inlaws, I realise how angry I am and then things tend to get out of hand.
So I am trying to deal with the anger as it is, since I am unable to change her behaviour at this point.
I would like to know about your experiences or success stories regarding anger management with your SOs with (u)BPD or BPD traits. Is there a certain technique that the pwBPD tried that worked?
I hope this post is not very out of place here; if it is please feel free to tell me so

Best wishes to you all,
Polly
