I'm glad you found a meeting and are willing to go. You don't have to say anything tonight. People understand that and everyone is usually really nice. Stay busy so that all your thoughts aren't filled with your fella. It's easier said than done. You might also want to get to the bookstore or library and get a book by Melody Beattie. She writes about co-dependency and how to step back and take care of yourself. Everybody talks about her books here so I ran out and got one then a friend sent me another one and I never want to put it down!
Good luck. Let us know how it goes.
Good for you for not waiting around when you dropped that stuff off. I'm sure it wasn't easy!
