The real question is: Does he WANT to learn?

I was in a past relationship for 6 years and she just handed everything over to me and never really cared. She had bad credit, outstanding loans, etc.

It drove me bananas.

In my current relationship, I sit down with my girlfriend and we talk about our finances.
We've seen each others credit reports/scores and know each other's balances.

It's a whole different ball game when you have someone who is playing as your partner on a team rather than just being the coach to a player who doesn't want to win.
