Hi Smeagol
I've been following your post since the start and can identify with some of it myself, having been on the receiving end of a lesser degree of emotional abuse. I think you're doing really well, and think it would be great if you didn't have to go home after this weekend! But I know that small steps are still best at this stage.
I wanted to comment about the thing that happened last night - I agree with PP that he has indeed sensed a change of some kind, and is upping the control a little to see if he's still the boss. Normally, having talked you into it he'd then get his way, right, but this time he didn't? This is adding in a new factor to see how you'd react, i.e. getting you 'ready' then further dominating you by withholding the action. I think that if he'd really wanted to appear caring about you not being in the mood, he'd certainly not have laughed and walked out of the room. That is showing contempt for you, as well as the statement that he'd had a wank earlier, i.e. he doesn't need you (tonight) but you need him (because you're 'ready' for it). Has he ever cared if you're not up for it before?
Sorry if that sounds harsh, but you need really to see his behaviour for what it is. You said it made you doubt yourself, but that is what EA does to you. You doubt yourself, you lose confidence in your own judgement, you depend on them to be 'right' about everything as you no longer trust yourself, and all the while your self-esteem drops through the floor. It really is the Death of A Thousand Cuts, as your self-worth is chipped and chipped away until there is hardly anything left of the real you.
But you are lucky, you have caught this in time and are actively doing something about it. I know you have had good advice on here, and you have been speaking to all the right people, so the only thing I would like to add after your last post is to ask you to please not question yourslef based no anything that he has said or done. If he does something out of character, ask yourself what he is up to now, rather then doubting your reading of the situation. You will be right.
Enjoy your weekend of 'freedom'.
