I had a night like that. At one point I was seriously considering moving to Colorado and living on my own there. My husband was very nice about the whole thing. It was to be a separation, not a divorce. And he kept asking me questions about what I would do, where we would live, gettng me to think of more and more details. We were lying in bed talking about it, and I was thinking hard, really imagining being alone with the children in another state, trying to support myself, etc. And I started hyperventilating. I suddenly couldn't breathe. And then I started sobbing. sobbing and hyperventilating. This had never happened to me before. I always thought of myself as very strong and able to face adversity. Anyway, I took the for sale sign off the house the next day.
