Hi NM, Glad to hear you have covered yourself -- the research shows that women tend to "give away" too much at the outset out of kindness. You don't want to presume that your husband, who promised so much, would bail on responsibilities but it happens so often. I think sometimes that's because they are cut off from their kids (unavoidable to some extent when you've left -- or been kicked out of -- the home.
Legislating dads' involvement is a good step forward, but every sitch is different and it can't replace them in the home.
