I think that if selling the house and going your separate ways is inevitable that you'll feel better having it happen sooner rather than later. It will likely be worse on you having to hang around with him knowing it's only temporary...through the holidays.

I think your attitude sounds good. You sound strong. Taking control of your life rather than waiting on his whims is helpful. Best of luck.

My ideas of goals: Focus on your D. Try to figure out something with your step-D. Find an activity you enjoy. Maybe a fun church group for singles. I don't know.

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.
