It's a long road with many twists and turns. Some days will be smooth sailing and others like you are hitting moguls and potholes. The most important things are for you to take care of yourself, be patient with yourself and think of yourself and your kids FIRST.
Unfortunately we don't control the time in which it takes the other person to come through their crisis to the extent that it goes faster. So it is important to work on yourself by getting a life.
Go out and do something for you, even if it's just taking a walk. Folks here have great advice so check in often.
