Minor setback. The "you look nice" comment might not have seemed well received, but on the heels of her angry at you it might get her thinking. She was in the midst of crabbiness and had recently lashed out at you and you compliment her. It will stick with her that her attitude didn't crush you. I'm sure at this point she's where she wants to keep you at arm's length. I think there is a fair amount of that behavior because if our s/ex-s relaxed and went with the flow they might find themselves loving and "giving in".
Just keep that PMA up at any cost. When she is at her worst is when you need to be at your absolute best, not when she is at her best.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
