Jenny,
You know..you don't have to take on all the responsibility that your H attempts to dump on you.
In the mortgage situation, you could have tossed the paperwork at him and turned it over to him saying "You can either do it yourself or we can do it together but you can't dump it on me and then get pissy about how I'm explaining it." And leave it up to him. Stop trying to smooth things over, it just makes him worse.

Fwiw, I had the exact same thing happen with my H a week ago or so. It seems that men have a problem having something explained to them by their wife, most especially if it concerns finances..? The difference is that my H calms down a lot faster and isn't adept at all at throwing out verbal jabs.

Anyhoo, please give that muthafreaker a message from HP:
