Ms. H, I'm sorry to read that you are having some down days. You know, maybe it's best to sell and move to a new home. It will give you and the boys a fresh start and your xh will have absolutely no control over that one. He will have to knock or ring the bell to enter as this will be new territory and territory that belongs to you and the boys. No more free entrance passes.
It will also give you an opportunity to declutter and get rid of things that you no longer need or desire to keep. I know, it's a tough task, but one that will need to be done. With the market the way it is, you may be able to sell and purchase something really nice within your price range.
Things happen for a reason and I suspect this chapter of your life is coming to a close, but that doesn't mean that the new chapter is going to be worse...it just means it is time for you to live your life to the fullest w/some exciting changes coming down the pike. Ms. H, it's time to spread your wings and soar!
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.
