Did Mr say ' I want a Platonic M.' or did he state a fact and say 'Our M is platonic.'

??

I think its pretty obvious what he is saying. He asks you for various(FITB) instead of telling you, just like he ASKed you, (Not TOLD) to marry him.

He has felt neither respected nor appreciated by you for a long time.
You guys didnt work towards mutual caring when things went south, you Juiced each other.
So your rose colored glasses are off. Now what?
Do you want desire? Go get into a New R. Ive no doubt you will be able to bounce from R to R to get and feel the 'real' feeling of desire again.

Do you want a healthy M, and intimacy with your H? quit fixating on what you dont have.
He isnt going to force or require you to do .... (frankly Im glad) His environmental training and education dont allow for it.
Since he isnt going to force you, that leaves you with choices. Which he is giving you.

What you gonna do with it?

I disagree he is being P/A.

What is the last thing he asked you for? When was the last time he asked you for something? (and I dont mean --would you pass me the milk...)

Then again, maybe the path you are headed down, will give him the impetus needed to learn what he needs to learn. Im sure his next W will appreciate it.
