Heather, One more thing, there is an old saying that I use periodically on here when posters "watch for signs" that their spouse is waking up...that saying is "a watched pot never boils". The longer you watch for changes, the longer it will take and you just might miss something else along the way while watching that pot boil. That's why it is important that you keep the focus on you and your girls. Your girls are growing up fast and your older daughter will be going off the college. Now is the time to spend as much quality time w/them. They are growing up fast and once they are grown, you can't get back their childhood again.
Now is the time for you to do the things that you've put off doing for a long time. It's time to spread your wings and soar. It's a time to try new things, create new traditions, etc. When you leave the pot alone, eventually it will boil and you will know if and when he actually does see the light because he will begin reconnecting and doing the things that he once did. For now, leave the pot on the stove and allow it to boil.
I urge you to read the postings in the archives or even go back and re-read the threads that Cadet sent to you when you first joined the forum. You will find a wealth of information in them that explains some of what your h is doing in the way of crazymaking behavior.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
