I, I would do the fellowship. You worked extremely hard for this and you shouldn't allow your h's crisis ruin your opportunities. I realize that you are concerned about your daughter, but this just might be the break that all of you need to heal and get back on your feet. She will still see her father and be in communication w/him. Who knows....he just might appreciate her being his daughter if she's out of his sight for a while.
Think about it....I think you should do it!
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.
