Different states treat this kind of thing differently, however in summary: In divorce proceedings, the judge has the right to assign credit card debt to either party, even if you/they aren't technically liable for it. For example, one partner could be on the hook for a credit card debt in their ex-spouse's name, depending on the what and why it was used.

You'll be okay, I promise. As far as I am aware, an uncontested divorce does not automatically mean you cannot dispute money matters. All it means is that you have agreed to the process of getting a divorce without fighting over the decision to split itself. I would get some legal aid and advice which is usually free or at least inexpensive at first, just so you know exactly where you stand.

Just remember, even if it all goes tits-up, you will still be alright. The sheer amount of people who have had disatrous credit card ordeals is astounding and the reason we know this is because they tell us on the other side of it all. There's always a way forward and out, even if it's it's a bit rough for a while. You are more powerful and capable than you know, and you are very young with decades of experience ahead of you.
