Grizz, have you thought about how W would view whatever you tell her:
Choice 1 Grizz: I can't change my schedule at work. W: He doesn't support me. He's not behind me. He can't compromise and find middle ground with me. This confirms it.
Choice 2 Grizz: I can adjust my shedule at work. Let's work together to see what works best for both of us. W: He supports me and believes in me and is happy for me in my new job.
Don't know exactly what your W is thinking or would say. But it might be something like the 2 choices above.
If you want to work towards reconiliation with no guarantees it will happen - Choice 2
