You can talk to her when if you are all alone in the house and make sure no one is listening to you.
Maybe your girlfriend isn't over her ex husband.
As a friend.
does she stare at you talk to you all the time smile at you
to me, that means she isn't over her ex yet. she needs time to reflect on her relationship with you and her ex.
No, unless she has asked you not to.
There are no good comebacks for ex's.
Only if you are sure that you will never talk to your ex girlfriend again.
hopefully your friend is a good one and doens't go with your ex. You should talk to him about it though. Tell him your going through a hard time with the break up and if he is going to go out with your ex, to at least give a little bit of time.
Give her space for a few days
don't talk to them unless they talk to you
If she was real, she will not become an ex.
Tell ehr it makes you uncomfortable when she talsk to her Ex
