relationship

I don't know why people do this. Maybe they think it's just good natured teasing. That may be the spirit in which it is given, but I've never known it to be taken that way. You might have a talk with her about this, and let her know how it affects you. Not right away, of course. Let everything cool off.

HOW does she talk about your ex? with curiosity, anger, jealous remark, making jokes?

Maybe she just wants to know about the relationship and why it went bad.

Girls like details like that. Besides, it gives her a clue as to what you do and don't like.
