Herrena here's what Susan Forward says on this scenario in her book "Toxic Parents":
"I said I was sorry what more do you want?" Some parents may acknowledge a few of the things that you say but be unwilling to do anything about it.
YOUR RESPONSE: "I appreciate your apology, but that is just a beginning. If you're truly sorry, you'll work through this with me to make a better relationship."
Charlie It's a personal decision, and there's no one-size-fits-all. You'll find what you're comfortable doing wrt to your relationship with your parents at your own pace. If you say you're uncertain about cutting contact at this time, then maybe it's not right for you, or maybe it's not the right time for you yet. Or maybe you're thinking about it because it's what you really want to do, but taking the plunge seems daunting.
I cut contact with my parents 4 months ago. I spent a year beforehand processing my grief and anger, journalling, writing them angry letters in my head, throwing crockery at my garden wall, and going to therapy. Then one day I just wrote them an e-mail and sent it; yes I explained why in it. It just happened spontaneously, the words just flowed and it took no time at all. It was pretty short: I didn't need to emote in the e-mail as I had spent a year doing that to myself. I just exposed how their past and present behaviour affected me, with examples, and told them what I expected now: no contact. Their reaction proved to me that they remain incapable of hearing me or respecting me as a person with my own feelings - confirmation that I had done the right thing, if you will.
From my side, there are no feelings of melodrama. Frankly, I am happier now than I have ever been. They are not "dead to me" or anything like that: they are just people whose behaviour has damaged and disgusted me, I find them unpleasant to deal with, and I know that I am happier without any kind of interaction with them.
