Should I go or not? Family Do

[onedge]

Hi all,

My sons birthday is next weekend and I have been invited around to my WAW's place for the party, I'm not really comfortable with going because
1. My email a couple of weeks ago upset her family a lot.
2. My WAW flirts a lot, and there is a guy who will probably be there who she seems to have a EA with. I'm not sure if I should go,

I have my kids that weekend so I will be taking them when i leave, which means I will be there untill 9pm or so, and if it's anything like the other birthdays all of the guys will stay at Ws place and get drunk which i can deal with right now, but when I'm there I probably wont be able to.
I'm so unsure about it all that i'm feeling sick even thinking about it.

Any Ideas?
