My childhood was chaotic. Mum and dad divorced. Mum married again, divorce. Married dad. They never resolved their issues. Regularly screaming at eachother into the night until I called family members to come round.
Mum's mental health wasn't the best and she threatened my dad with killing herself and us, if he tried to see us when they were together. She was sectioned a couple of times. While we got shipped around different family members
Wider family claim to not know it was that bad.
I don't know if I have forgiven but I have made peace with it. Though I can't be 100% sure that I am not just very good at compartmentalising it.
I did manage to say my piece to my parents, twice, about 10 years ago when they went through another rough patch and were discussing divorce. Mum admitted she wanted to punish him for leaving, which was over 30 years ago.
I told them both they ruined my childhood between them. I also told Mum (who claims 'but we love eachother' that love isn't trying to punish someone for something they did 30 years ago and make them miserable for the rest of their lives. I told them they were pathetic and if they couldn't get over things that happened last time, they should have never remarried in the first place then at least I wouldn't have spent most of my teens stressed and exhausted. They both sat their like naughty children. Mum did go to therapy on the back of it and then they went together.
They seem alot better in recent years. The therapy seemed to have helped and let them air their problems and move past them.
I parent in a very different way. Which Mum wasn't a fan of. But a recent situation with my daughter that I handled my way was resolved and she admitted that she actually admired how I handled it and played the long game.
Again tbe therapy seemed to really open her mind to the fact that her way isn't the right way.
Unfortunately, I am now guiding both kids through issues with their dad. Him letting them down and not being stable, jumping from woman to woman that he insists on introducing to them. Dd has stopped seeing him, ds is going less and less. I have learned to not let them see my anger or my disgust at him. And just support them.
I actually have a decent relationship with my parents now. I speak up when Mum starts being arsey. Her latest is that my generation has it so much easier than her. But now it's a discussion where we both try and see eachothers sides.
I have come to a point where I think it is what it is. Mum grew up in a family whose dad was abusive, her mum never recovered from the death of mums brother as a baby and she has her own trauma. Dad was definitely neglected to a large degree and had an alcoholic dad.
At this point, I think most people causing trauma have some trauma themselves. I concentrate more on making sure mine don't get passed on to my kids.
