Oh EW you sound SO like me a few months ago (and even NOW.)
"I feel like someone is who is putting on a cold mean face because they don't care and is using the suggestion of EA to try and justify it internally."
I think this all the time. ALL THE TIME. I feel like a fraud for being here. Although I KNOW that DH did all the Bad Things, sometimes I think that he just didn't realise or was just inadequate. BUT THEY STILL DID THE BAD THINGS. Someone who is NICE and LOVES YOU will not do the bad things.
Putting stuff in writing - my DH made me do this too.
I agreed to an email he wrote which contained about 15 "clauses" of things we would not do for six months. Including not moving in with Nice Boy, not having things of Nice Boy's around my house, not introducing family/the children to Nice Boy, submitting receipts to XH for everything I have spent, how it is my decision to move out and end the marriage, etc etc. (Bear in mind that at the time I had not had ANY sort of physical relationship with Nice Boy, DH just knew that he "made me feel safe" and was the trigger that made me question why my HUSBAND made me feel THREATENED.)
At the time I thought that him asking me to put everything in writing was perfectly reasonable behaviour.
OMG. It is MADNESS.
"This is an awful thing to admit but I don't want him to change his behaviour now."
I know, of COURSE you don't. You have DOUBTS which are normal - partly because he has made you think that perhaps you are BONKERS. You are not. My XH is now as sweet as pie and doing all he can to help me - although sometimes I still shake with fear when I see him. That's not NORMAL!!
"I so want to get the Lundy book ... but if H realises I am reading it he will flip."
Of COURSE HE WILL. Because he won't ever accept that he is That Man. He will just use it as evidence that it's YOU that has lost the plot and are now imagining things, when he is really lovely and kind and loves you.
At few months ago, I was talking to a friend about my marriage and she said: "At the end of the day, you will do what you want to do." And I felt SO RELIEVED. Because I knew that what I wanted to do was LEAVE. And I did.
YOU HAVE EVERY RIGHT TO END THIS RELATIONSHIP WHENEVER YOU WANT.
