Oh Wow, that's a great compliment! You are doing a great job, and it's obvious to everyone. I'd tell her "thank you" and leave it at that however. You must feel that you are on the end of her yo-yo and statements like that can put you on a high. I suggest that you accept the compliment but don't let it draw you back in.
Remember your goal - if she wants to patch it back together, it starts with pastoral counseling. That's my first step also if my wife turns around. So far, she is not, but I can accept that.
