Hi Jboy.
I would keep giving her space. If she reaches out, keep the conversation light, no more apologies and no pressure to get together or even talk about it. Take things slow. Give yourself and her time to recover. For you, use the time to work on yourself and take a look at why you did some of the things you did when you were together and work on changing them. Learn to manage your own anxiety and fears.
If you post here about that sort of stuff we can help you. Working on you is important because if you get back together now, neither one of you have changed in a significant way and you will be going back to more of the same. So take the time to workon you and post here.
