B, good for you.

She needs to see consistent ACTIONS from you. The way you get there is to really believe in the changes you want to make.

If you keep telling her you've changed and then react in a way that you have in the past, she is thinking, nope, he really hasnt changed at all.

One of the most important things if for her to feel that you've heard her.

So, if she is telling you that she needs space and you are answering isnt there another way, well, you havent heard her and she gets mad.

Tonight you are getting an opportunity. Take it.
