WW in MLC affair and I need advice..

[Natash]

I have a quick question I'm looking for some advice on. Last night WW went out to eat from 4pm to 12:45am with "a friend who is getting done at work". This morning when preparing for the day, I was quiet and out of her way and didnt ask any questions. As I was getting to the fridge to get my lunch ready she hurried by me put her shoulder into me. I said "excuse you" without any attitude and D7 is in a nearby room and says "why are you guys acting like brothers and sisters all the time?" I did not know what to say to her. So I got thinking, should I be engaging with my WW when she returns from these outings,asking if she had a good time, etc? I haven't been as I saw it as a form of pursing (I don't mention anything, I act if nothing took place that I care about) but wondered if I am handling it the best way for me as well as my daughters?

On a different note, so looking forward to these next 7 days with new friends, wilderness, and good times but most of all a break from my WW, her actions, and lifestyle!
