Hi Aldo,
I totally agree with what Anna said , being sober, you now CAN choose where you go and what you do. I did not have that choice when I was drinking, and was the biggest people pleaser known to man !
Having said that, if you feel that you should go, remember that you can leave at any point, or just go to the Church and not the restraunt . I had a similar dilemma when I was very newly sober, and I made sure that I took a couple of phone numbers with me, of AA friends, I also arranged for my Sponser to ring me on my mobile, in case I needed an "escape".
The choice is yours , but i consider my Sobriety my most precious asset, and will not risk it for anyone, or anything
Good Luck
HUGX
