I woke up upset too. Looking at what he was saying....I guess he is referring back to a lot of things in your previous R, before the S (I thought you werent supposed to be doing that??) and now looking realistically at what you had then and what you might have now.. I know you have changed from what you have told us, he may not have noticed, or maybe he doesnt believe you have, or maybe, he doesnt trust that the changes will stick. Like the DR books say, the WAS needs time to grow in confidence that you have changed and that things wont be like they were before.
I have changed too.. but maybe my ex hasnt (still weak, indecisive, avoidant, bad at making decisions etc) my BFF wonders if me and my ex wouldnt end up falling back into old patterns eventhough I wouldnt want our R to be like that, if we had got back together. Maybe you and him are falling back into old patterns now becuase he hasnt changed?
