Definitely keep moving forward with your plans, good start from him but this is very early days and the future/his recovery is still very much uncertain.
I was taken in by my AH proclamations- it hasn’t turned out so well for us/him and we’ve been apart now since January- I was riddled with guilt and doubt at the time but I am now SO SO glad that I pursued the separation as much more has been revealed in that time.
It’s painful but progress will be made
