Reading your post, on your after party discussion, I keep asking myself, how is this any different from your want/desire/need to get hubby on board with primal. All I can come up with is, they're the same thing, differing only in specifics.
I think it might be enlightening, and possibly helpful, to point this out. Then try to agree to let both of you decide what is best for yourself, keeping the best interest of the marriage at the forefront of all choices.
And for what it's worth, I know about sacrificing dreams/careers. I gave up a career I had wanted/sacrificed for since I was 6 years old so my ex could pursue his. No attempt was ever made to support me returning to my career.
To this day, he has his job/career because of the choices I consciously make on a daily basis. His lifestyle/financial security is 3 times mine because of my contribution.
I am now very vocal to my daughters about NOT putting all your eggs in someone else's basket.
