Let her have her space. Don't wait for her, but it's *possible* that she'll date once or twice and feel like she left what she had with you for no reason. Again, don't wait for her, but just move along and know that if it's really "meant" to happen, it will happen. If both parties aren't fully into it, you don't want it getting forced anyway.
So, keep the communication to pleasantries and "how are you doing"s and go from there. I'd say keep the sex out of it unless you just want a repeat of the problems for which you're now seeking help.
