Hi, this is Petra. Once again, I have reached the totally opposite conclusion from the other recent posters. She wants to go ahead with it, but can't believe that you are OK with it and wants to give you every opportunity to back out, both as to the entire idea and any specific guy. Like me, she can't believe her luck and your love. Unlike me, she is hesitant to act on it.
It may be good to take it slowly, but your hesitancy has gone on too long and is now getting in the way. Admit that you would like her to do it and tell her that it is up to her to choose when, where, with whom. You guys have made so many starts you are teasing yourselves as well as us here.
