If you share a credit card with someone, they'll have to add you as an authorized user.

report could take a hit. Credit reporting agencies might be willing to
delete that negative history if you ask them.Over at Credit Sesame, they give some tips on some things you can do to remove negative items from your credit report. If you aren't liable for the debt on a credit card, then it shouldn't be on your report—but even agencies can make mistakes. Credit Sesame suggests first removing yourself as an authorized user on the card. Then contact the agency and ask them to remove that item from the credit report.
