I asked each other, do you regret marrying me? She said there was no regret medicine. Is he implying regret?

It depends on her usual personality. If she likes joking at ordinary times, it is probably a joke. In addition, generally speaking, a woman's heart won't tell you directly, and even if she really regrets it, she won't show her cards directly when you ask. And if she really regrets it, it is estimated that you can feel it from other behaviors. If everything is all right, it can be considered as a joke.
