Quoting KAW: Acting "as-if" can play a big part here as well. Act "as-if" he might be a little nervous in the beginning of the occasion. That he might be worried about making sure you have a good time. This should help keep you maintain an upbeat and light-hearted PMA and ease his mood and make him feel more comfortable. Maybe even come up with a "ice-breaker" ahead of time to fall back on to help if things seem tense.
KAW -- Thanks for the welcome! Also, thank you for reminding me that it's possible that H's "presentation" may be rooted in far different things than the evil-ow stuff I ASSume. One of the things that I've been trying to work on (with low success apparently ) is not always ASSuming the worst -- heck, I shouldn't be ASSuming anything AT ALL! And, acting "as if" in regards to something positive (heck, maybe I'll imagine that H is distant because he's so dazzlingly in love with me that he has to keep a distance!) needs to be employed!

Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
