I know some of the feelings you are probably having - about XH and him being happy in CA and now someone else in your life!
Take it easy, hang in there. 2006 has to be better than 2005!! Good for you about sharing your happiness!
Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.
