I told him it wasn't appropriate for me to go and he insisted. Everyone there was really nice and I think they could tell I was uneasy about being there. My dad is a recovering alcoholic and goes to AA so I know the rules and go to Alanon. I haven't been back to AA since and I told him after the meeting it's all you now and he's been going on his own since.
On your last point, my intent was date casually and given all the commonalities between myself and the other guy it kind of progressed faster than I intended. When my ex came around it hit me that my feelings for him are still way more than they should be for me to have a successful relationship. In short, I wasn't as ready as I thought I was.
