Lets play devils advocate for a moment and imagine that he is genuine in the nice moments.
Time has proven that he is only nice when things are going his way, or when he is in a role that makes him feel good about himself because he is the centre of attention.
Its real easy to be nice when everything is going along swimmingly and there is nothing that annoys you - and makes you feel like other people are more important than you. This is fundamental to his character. Beyond the Game, he is someone who feels as if the world should centre him. Its that belief, deep down, that allows him to consider The Game as a manual for 'success' rather than an abhorrent rape manual.
And the problem is that life doesnt always go to plan, and you cant always be the centre of attention. And if you are someone who believes that they deserve that, you cant help but pull everything back around to you - even yesterday - YOU were having the terrors, but it was all about how bad it made HIM feel, and how he wanted a clean start so he could encourage you to move on from those feelings that affected HIM. That shows that its not really about your feelings and well being, its about how your feelings affect him.
And you see how he gets if things dont run to his tune. If there is noise, and mess. He flies off the handle, he cant control his emotions. And if its not about him, he sulks, or makes arguments to ruin things for whoever it is about, because he cant bear for anyone else to be the star. How is that going to work out with the kids? With big events in their lives, or even small ones. Will they need to shrink so as to not outshine him, or will their successes always be seen as a reflection on him, and how proud HE is. Ive seen this so much - usually men, who want all the congratulations and 'you must be so proud' while the child who achieved it is ignored or just rolled out as a trophy.
I think what Im trying to say is that his basic character is entitled and self serving. That is, deep deep down, so woven into his being and feelings of worth, into his beliefs, that he is not capable of taking the good with the bad, with surviving lives ups and downs and acting as part of a family unit, with the give and take of allowing each member to flourish. So even if, in the moment, he genuinely believed he could change and be different, he would really really struggle and find it far too difficult to do so in practice.
As Lundy says, this is work that would take decades to unpick, its hard deep soul searching work, its facing the dark elements work, its looking yourself in the face and seeing the truth work, and then fundamentally unpicking everything you have known and believed since childhood about yourself and the world, and rebuilding from scratch type work, and its no wonder that very very few men are either capable or willing to do that. Plus Lundy stresses that this work should be done away from the person he has abused, with absolutely no expectation that the relationship would ever reestablish.
So if he were genuine about change, and if YOU wanted him to change for himself, it wouldnt be while you were together. It would be kinder to leave and give him space to do that work and for you both to move on.
But I dont think thats what he is saying, honestly, is it. He wants the status quo. He wants you to forget about the past and move on. He wants to be able to pop to a counsellor and ask how to stop you going on about it all, if that, and maybe a couple of CBT type relaxation techniques to maybe hold his temper a bit. Minimal effort maximum result for him.
As I say, I expect he will try REALLY HARD (ie deliberately choose to hold off) for a week or so. Enough to try to convince you that everything is fixed now and that you dont need the therapy anymore - after all it seems to be making you worse, doesnt it - he;'s NEVER seen you like the other night, it really frightened him, and he has so much concern and care for you, he hates to see you like that and cant bear to think of how awful it all is for you. Why stir things up, after all he told you right back when it happened when you were at college to let it go, that its best to move on and recover rather than stirring up all this horrible stuff. He just wants to care and protect you. You are so vulnerable, he is scared that you will break, and then what will happen to the poor children when you dfo that to yourself.........
