I don't even feel I should need to apologise to him after going off verbally on him when I feel the intense disgust.
If one berates the WS as a POS, a terrible person, irredeemable, not worth the air they breathe, etc. - that is, if you attack the WS - maybe an apology once in a while will be appropriate.
If, however, you express your rage in terms like, 'I'm furious that you did _____,' you may never need to apologize, because all you're doing is sharing what you think and how you feel with your WS. If you're honest about your thoughts and feelings, what apology is necessary?
Besides, telling your WS what a lousy person they may be gives just a moment of relief. Sharing your anger lets the anger go.
'Sharing feelings' means using words, tone of voice, and body language that show your feelings. Anger, grief, fear need to be shared with more than just the words.
Also, being betrayed brings on a LOT of feelings, so expressing anger, grief, and fear may be necessary again and again and again.
I feel like he should be constantly kissing my feet for not immediately kicking him out and never speaking to him again.
I think a big portion of our success in R came from my W's focus on solving her own problems, and that took energy away from catering to me.
IOW, she cheated to get external validation, and she cheated out of co-dependence. She was afraid I'd leave her if she didn't read my mind and give me what she thought I wanted - and she misread me time after time. In the end, she healed because she asked herself why she wanted to do something for me. Was she giving it to satisfy a need of her own? Did she need to give it whether I wanted it or not? Was it a real gift, or did she have an ulterior motive?
If she wanted to give me something, she learned to ask me what if I wanted it. She learned to say 'no.' She learned to ask for what she wanted. By asking explicitly, she recalibrated her reading not of my mind but of my non-verbal communications and allowed my to recalibrate my reading of her non-verbals.
Some examples:
She might say,
'I want to _____. Is it OK for me to do that now?' Or,
'You look like you want a hug. Am I reading you right?' or,
'I can't interrupt what I'm doing. I'll be with you in 30 minutes.'
My point is that kissing the BS's feet may not be the best approach where the WS's co-dependence is part of the reason for infidelity.
BS heals BS
WS heals WS.
Together, they build a new M, if they want to and if they do the necessary work.
