Am I in the wrong?

So here's the story. My husband paid off my car last year... He recently took a $5 pay cut for a better job (sounds weird I know... Better for the future).

Now we're broke for a little bit which we new we would be and it would be a hardcore test for our very young marriage.

Well he works two jobs and I just got a second job just started today. He feels I should help him out now and pay for the rest of his school bill that the union is not picking up. When he has a second job that goes to all of the fun stuff he wants to do and get.

But my extra checks have to go to pay stuff off?!

Am I not seeing something? Am I in the wrong for telling him no? (I told him no and now he's pissed at me because he paid my car off a year ago.)
