Dont ask about the other guy, dont even hint, forget about him, you obviously won.
If you want to date this girl then you need to show her the emotional connection NOW or else she will start to drift away... Not sure if we already talked about it in this thread but you have to make sure to make that connection quickly.
Show that you are fun to be around still, not that you just want her for sexual reasons, so make sure to do other things with her.
Keep yourself interesting, hopefully you have a few dhv's that you haven't used/told yet.
Well done, and good luck.
