Golfgirl,
You are the only one who can determine when enough is enough. If you reached your point of the same then taking care of yourself emotionally and financially is exactly what you should be doing. Be good to yourself. Allow yourself to feel what you feel. No one likes to see a divorce happen but when it does we try to offer support as best we can.

Look not mournfully into the past. It comes not back again. Wisely improve the present. It is thine. Go forth to meet the shadowy future, without fear. {Henry Wadsworth Longfellow}
