Well, that could be a bit tricky...
One advice would be to just forget about her. It sounds to me like your game is tight, so forget about having sex with her if it is just for your ego. There are some women in my life I have dated that I never got to fuck, and the best thing is to simply let it go.
If you are determined to have sex with her however, you will need to make some contact with her and the gauge her interest based on that. Don't come on too strong at first; you really hurt her at one point so keep that in mind. Chat with her, "how's it going", all that. If she responds positively, meet up for coffee. If not, let her go.
I have never been in your situation but this is how I would respond

let us know how it works out for you!
