Little it is a backslide but please don't beat yourself up over it. Also you are spot on with apologies. In the future you apologize ONCE and ask yourself for forgiveness and the good lord and move on. Do not keep apologizing for stuff. You apologize and now it is on him. Ok?

Take the above experience ^^^ you speak about as just that. Experience.

What did talking about relationship stuff get you? Nothing. If anything more anxiety.

I can see your husband feeling guilted and/or manipulated about you bringing up the kids behaviors. I know my W did. Try not to do this. I think he knows it [censored].

You need to focus on yourself ONLY. Start doing work on yourself. Take care of yourself. Can your husband take the kids from Thursday to Monday so you can goto EE? I think you need this more then you know. Don't let yourself go a year plus like I did without truly doing your work.
