My girlfriend WeChat, who has already broken up, contacted me to chat and said that she would give me a birthday present. What does she mean? Do you want to accept it?

I think she wants to get back together with you As for whether you accept her birthday present, it depends on whether you want to fall in love with someone else again. Here, you should consider why you broke up. If you don't think it's necessary, that is, you really don't want to fall in love with her again, then you don't want anything from her, and politely decline.
