I've already had that conversation with her Mom, Dad, and Brother :)
Yes, she knows it's coming, just not when. If things are as they were last I checked, she thinks I'll be asking sometime in the spring, so This will be a nice surprise.
I think that's the way is is with all couples who are at/were at this stage. You have to know each other in and out, and it has to be perfect for both of you.
