I kind of agree with Koliver, Lauryn, in that exploding after 13 years of suffering in silence (if that's what you did?) is unlikely to achieve the result you hoped for. Though, in a way, it did work for you didn't it? He picked you up when your car broke down, so at least he got the message
I do, however, feel that you're justified in feeling angry - and disappointed. A marriage is supposed to be a partnership. Partners help each other out when they're stuck; they don't just go "Your problem, you sort it."
If I were you, I'd try and leverage his recent
helpful act, by telling him you appreciate the fact that he's heard you on this. Thank him, and ask him to step up next time you ask for help, too ... and keep on doing it!
Just a thought: By now, you may have become so resentful about this, you've stopped bailing him out when he needs you, too. Can't say I'd blame you, if so, but this is the ideal time to put that
mutual support back into your relationship.
Good luck
Let us know how you get along!
