Well, firstly, sometimes we hear blame where none is intended. We hear blame and try and minimise and deflect when all the other person wants is for their pain to be acknowledged instead of dismissed or invalidated.
Could this be happening? Because someone can still be in pain, or even quite damaged and / or traumatised by past events AND it be completely true that another person there at the time absolutely did their best with the information available.
It’s not a fight to the death for legitimacy. But if you feel so hurt or blamed by this other persons pain, then you could be making it a case of either Your Truth, or Her/His Truth... because you don’t want the feelings that go along with acknowledging that BOTH can be true.
I don’t mean that namby pamby ‘truth is somewhere in the middle’ stuff, which is problematic as it sort of feels like it means neither of you have a right to feel how you do. I mean that literally both of you can feel the weight of your own emotions and hurt and needs and everything, at the same time, because more than one person can be right, or wrong, or suffer... it’s not a binary type of thing. Unless you are an abuser.
My caveat is that I’m the case of an abusive parent or other adult in a powerful position, you do get to be held responsible for the harm your abuse did to a child. But then, the type of person who chooses to abuse their child, week after week, month after month, year after year, well, they aren’t going to learnt anything from a couple of joint counselling sessions and I would question why that situation was happening. This is the reason I would never unburden my soul to one of my parents, although I’ve had a lot of counselling. She will be screaming victim to the end, and lacking insight over her actions as she’s not capable of being anything more than she ever was. The only person that would get hurt in that situation would be me, giving her more of a ‘victim’ status in her head, with me attacking her and being so unfair in a counselling session. She would never hear me.
Obviously I have no idea what scenario is nearer your situation, but if it’s the latter, it will become clear very quickly, and if its the former, I hope we can help you.
