I am with Dee. I'm not sure I'm understanding the need to spend time with her at all after this.
I definitely wouldn't be going on vacation with her. I think that this recent dinner would have to be my last time with this person.
I stopped spending time with all my heavy drinking friends and anyone who does any type of drug. I can't rely on them to watch out for my sobriety - that's my job, so I have to protect myself. Plus they're just not fun to be around. They get repetitive, loud, overly-sensitive, argumentative. I don't like that kind of drama.
