If you don't want to hear about her comings and goings then ask your friend to stop. It doesn't really help you any now you have established what the situation is.
In one of Michelle's books it talks about the stop sign, everytime a negative thought comes into your mind mentally hold up a big red stop sign. I found that really helped. Also distraction, enjoy your weekend with your children. Your weekend is only ruined if you let it be and you are in control of that.
Honestly start posting to some other posters on the board and you might get more help. You get what you put in and all that.
