Why do you have to bring it up?
I think sometimes just letting sleeping dogs lie is a good thing. Let some time pass, keep quiet, stay happy, plan a vacation. Be romantic, have more date nights, enjoy your lives. When the time comes if it does you can talk about it. Until then really work on solidifying your relationship with her.
If she's crazy in love with you and enjoying the new you, happy out of the borg, then she's probably more likely to want to be with you. If you're miserable, act depressed, always want to have these debates over religion, it's not going to be that much fun.
When I left I didn't deal with it for years. I literally just didn't think or talk about it all. When the time came and I was ready I dealt with the subject on my own terms on my own time. I just don't think you need to force the issue. When she's ready, she'll talk.
