1) Try to get out of serious mode. This is serious business, but it gets old and is no fun if you only talk about the relationship. Go for it a bit. You initiate some hugs (or even more)when you see her. This is your wife. It isn't a stranger or the first date. Put yourself out there a bit. Get natural with her. I know this part is awkward, but it helps if you try to move things to a more natural phase. My wife stayed at the house ONE night, and it was amazing how quickly the awkwardness left. She never left after that point. If you have to keep seeing her for all these awkward little talk sessions I doubt it will be all that exciting for her. Just give things a go. Have her over....and soon while she's still looking positively at things.
