Kate, The hard part is beginning. Keep your expectations as low as possible and dig deeper for more patience. If you haven't read any of reachingHigher's postings, you might want to do so because she's on track w/her marriage now. T2 is another good example of working on his marriage w/his wife in the home.
Good luck and please continue to post. You'll need to come here to vent and/or blow off steam if he gets under your skin too much.
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.
