I know you don't necessarily agree with my POV but here it goes just in case it does prove helpful.

I will use numbers to illustrate my point.

Your W for some reason can't or won't give you level 10 emotional support. She can give 5 at most.

On the other hand she claims she doesn't want or deserves anything more than a 7 from you.

Her actions towards you tell me she expects a 10 on your part.

Through your 180's you have stepped up to a 10. Your W stayed at a 5.

Lately in order to get her to reconsider her actions you yourself have dropped to a 5 too.

Your W retaliated by going to 2-3.

Her counterattack is working since you are already second guessing yourself.

You'll back off go back to 10, she'll go back to 5.

If she really wants to get vicious she'll threaten to go WAW again.

My recommendation is to hold on at 5. Five being kinda where you are now. Once she moves to seven go to six, and so on and so forth.

I think you need to make it clear that your love is reserved for those that can and are willing to reciprocate.
