It's said that we need to put the oxygen mask on ourselves first - you'll be no good to anyone if you don't look after your welfare first...I think thats especially true of parents.
Your daughter needs a dad, Dub. Be there for her. Remorse for the past is natural, but whats done is done. We can't change a day of the past - but we can try our best to be a good role model from now on
