What does it mean when a woman apologizes for a joke I liked? Should I reply to her or not?

We were texting and she wrote a joke that was funny but I didn't reply back, neither I reacted. Some hours later, she sent me an apologetic text, asking me to forgive her if she made me feel bad with her ''bad joke''.
