Mozza, I wouldn't worry about W seeing your tears, you're only human after all and kids shows are emotional for anybody never mind with everything else going on. I think you did the right thing deciding to sit together and put on a united front for D. Surely your W must have felt some emotion too.
So sorry you saw W and OM together, I know how tough that is.
Please keep on posting, I love reading your updates and I also appreciate the advice you give to others.
Take care x
