A girl always says "hehe"! What do you mean?

Did she say hehe, or did she say something else at the same time? If it's just hehe, she may really laugh again, but at this time, there is usually an afterword. If this hehe sentence doesn't match the topic we just talked about, it's perfunctory or coping with you. Say something else, that's the normal tone. Actually, it should be a good thing for you to say hehe. Whether dealing with perfunctory, or just chatting, she did it, and made great efforts for Hehe. That's better than not saying it right away.
