True, Enjoy your garden...even if you are pulling weeds!
Enjoy the time you spend w/the opposite sex. Just remember, you are out having fun and certainly not out looking for a new life's partner right now. When the time is right, the partner that is meant for you will appear. Right now, you are just checking them all out. You aren't ready for anything permanent/serious.
As for your xh....give him time, he'll be contacting you again about something he wants to blame you for. Either he'll stop blaming you for all of his faults or he'll be one sorry, miserable individual for the rest of his life. But, that's his decision, not yours. Live your life to the fullest, for I truly believe life has some pretty interesting and exciting things coming your way when you are ready to venture further from your home.
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.
