Hey, welcome back Tim! Glad to hear the Vegas trip went well and really excited to hear the positive news. I echo GH's comments, I don't think the "coolness" is a good idea and is probably as productive as the pursuit. As with the kisses, hugs and ILY's, I'd probably say that those are probably safe, just not overboard. My W and I still do those things and she seems quite comfortable with it. Now if I start getting sappy with the "ILY more than anything.." type stuff, then I can sense the discomfort. Moderation is the best policy IMHO.
