Boyfriend Destroyer Follow-Up

Hi Bobby. First of all, I wanted to say thank you for your product. It's given me a lot of great insight and tips. Secondly, I wanted to ask for a piece of advice. 

I am finally seeing my "that one girl." She has been in a relationship since I met her (he beat me to it by a week) and I always tried to be respectful of that. After a few events in each of our lives and after reading and listening to a lot of your thoughts and products, things have escalated. We are seeing each other on the sly, and we have gotten physical. She is telling mutual friends that she's crazy about me, that she wishes she would have met me first, that our sex is the best she's had, etc. However, despite her unhappiness with her relationship and her increasing interest in me, she hasn't made the jump yet. Our mutual friends have told me that she's never cheated on a guy before, and that she hasn't left one guy for another since high school. I don't really consider her boyfriend my obstacle. I think my biggest hurdles to finally having a shot at dating her are the time she has invested in her current relationship (no matter how unhappy she is), and guilt over having never done this before. 

Should I just keep doing what I'm doing and hope that she makes that transition gradually over time? Or is there a more proactive approach I can take?

Thanks in advance.
