Great idea - I think I will look for belly dancing course near me. Something I've always wanted to do.
I think you are doing fine, nitaf. No R talks, he sees your changes, you are doing things for you, his being upset with your changes is normal. I think all spouses think "why now, after I've made my mind up." It's their way of saying, "I just came to a very difficult decision in my life, to leave my spouse, and now they go and change and I have to rethink my decision. Why couldn't they have done that years ago and saved me from all this heartache?" Yikes, how would you feel in their shoes.
Keep doing what you are doing, it seems to be working. Remember, patience. Baby steps is what you will see, not giant leaps.
