I've been divorced for 4 yrs and married to dh for almost 2. My ex husband is engaged. The four of us have a "cordial" relationship. I share 2 sons with my ex, and we all attend the same sporting events, sit beside each other, etc.
During those events,his fiance has started talking to me more about her future mil & sil (my ex mil & ex sil). I NEVER got along with them and the stories she tells me are so familiar. Is it wrong for me to engage in conversations like that with her?
