Sorry you missed the Al-Anon meeting. I hope you are able to let go of some of your resentments--they really are poisonous.
I always enjoyed AA meetings when I was in Al-Anon, but I can see if you are feeling freshly wounded from a relationship it might feel strange. A lot of the humor that sounds "sick and twisted" is actually a bit of giddiness that goes along with no longer having to live with the insanity of an addiction to alcohol.
I hope you are able to find a good Al-Anon group and get some peace for yourself.
