My ex-girlfriend often sends me jokes on WeChat. What does she want to express?

Maybe I just want to make up with you, but I don't know how to talk, and I'm afraid to chat with you, so I send some jokes, take the opportunity to talk to you more and slowly cultivate my feelings again! I suggest that if you still have feelings for her, you can talk like this, but if you are not in the mood to get back together with her, then don't do it, which will give girls hope.
