Breaking up (is hard to do-o)

Its hard for a whole new reason that I have just realised. When I try to break up with Neil in the normal way it simply "fails to compute" for him.

(1) How could someone not want to be with this paragon of manly perfection which leads to
(2) I must be mad

That's it in a nutshell. I have known for sometime that I absolutely do not want to be here. Intellectually, spiritually, emotionally - not to mention the dreaded morally. If I were to try to workshop telling him... (some of this has actually happened some has not -yet)

Fiona: Its not you, its me. I have been unable to accept what happened between us.
Neil: Well get over yourself. It happens in all relationships. What did your mother say?
Fiona: She said it happens
Neil: Well your mother is right as usual.

Fiona: You are not meeting my needs sexually
Neil: Well accusing me like that is very "Sexy" isn't it. The more you talk about it the less likely it is to happen.

Fiona: You are not meeting my needs to be part of a family
Neil: Well you gave that away when you got divorced. I can't be Connor's dad you know.
Fiona: Why can't we eat as a family? go to bed around the same time, get up together?
Neil: Sorry that's just the way I am. You can't change the way I eat and sleep.

Fiona: I need practical support help around the house
Neil: You just won't be happy until I'm doing it all will you?

I'm realising I will never "wrap it up" by nagging, or even improve it. Basically to him, this form of communication is just me having a head-rush. I need to be humored, firmly put back in my place (physically intimidated if necessary) because I am clearly out of order. Then life will carry on as normal.

So the upshot of it is. When the decision has been made, when I am bold enough. I have to just go. Not telling, showing. Which is apparently what his last fiance did, and he simply could not understand it. For years.
