True, You are not by yourself when it comes to nosy neighbors. I have the same problem, but not to the extent that you do. If your neighbor continues to ask about when you are getting things done, just smile and say, they are on my list of things to do. You owe him no explanaton as he's not paying for your place or the work to be done. People like that have no life what so ever.
Your xh reacted exactly the way I thought he would. He realized how he sounded after he said it and came back with a nicer email. Just be careful, for you have now opened the door for a return favor.
I'm glad you have been enjoying yourself. You need this much needed pleasant break from the madness you've been dealing with. Good for you!
Enjoy the rest of your week.
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.
