Married 2 years, husband doesn't feel "spark."

Welcome to the board. You'll definitely find the help you need here.

It sounds like you've figured out many of the things you need to work on. Right now he has to have the time and space to figure things out on his own. Meanwhile, try and incorporate the things you've learned into your every day life so that it becomes a permanent change.

For the interactions that you do have with him, be sure to not linger on the R. To him that's a negative. Talk to him like you did when you were first interested in him but not too clingy.
