Been away from my ex for a long time @Pollyotter but feared him coming back for years. I don't fear that now which is massive progress.
Yeah I get all those feelings - it becomes all consuming. I used to completely shutdown also - dissociate and not be able to move ...but at the same time as feeling numb feel everything as well .It is a really strange feeling because you would think they contradict each other but unless you have been through that it is hard to explain what it is like.
I do not thing you are weak at all - you are strong. It takes strength to get through what you did and to keep going - and that is what you are doing. Right now it is all consuming again but as we like to say here "this too shall pass". It is not and will not be easy but feeling as you do now in reliving everything is the worst it can get. We have seen (and felt) the worst of human nature - but there is also good to be found. Finding us here may be some of that good - you have certainly shown courage to talk with me tonight - so you should be proud of that because it is certainly not easy to talk to anyone, let alone a stranger, about any of this.
