I like your "me first" attitude. Actually you have been a martyr. Make sure that your actions aren't enabling your XW to have irresponsible behavior. It's easy to keep giving when you are in love, even at your own expense. I have done exactly the same thing after both divorces. I love your plan of action. Kayaking sounds fun. I might give it a try. Or maybe scuba diving.
Anyway, sounds like this is just what you needed to get the PMA up.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
