I don't know what you ultimately want out of your situation, but your emotions and fears seem to be in the driver's seat here. In a lot of ways your W seems to be sincere about putting some effort in, but at the same time a lot of the wounds you gained are obviously still very raw and emotions seem to bursting out.
I feel like you may want to do some damage control and hit the brakes a bit ASAP... perhaps mention to your W that you are still dealing with a lot of pain and pent-up emotions and you realize you are reacting very emotionally right now and want some time to cool off so you can talk with a clearer head. I don't know the exact words, but when you are running so high on emotions it's probably time to take a step back and not do anything else rash.
