At first I was thinking kiddos and not kitties...kitties definately make this less messy.

Are either of you being seen professionally for his possible bipolar or your depression? Is he aware of how this makes you feel. Although the comment, "...he has never to this day made that up to me." may suggest that you don't let him forget it. I was married to someone who was not really into the paying bills budget stuff. It was a definate strain to be "the responsible one"

I would agree that a good question to reflect on if you are happy in the relationship if the money issue didn't exist? If you would be...maybe good for him to attempt to sell that racing engine and give you a second honeymoon.

Good luck.
