Oh dear. Sorry to hear that nothing has changed for the better, although glad that you made it to al-anon. Shame that your lives have now got a whole lot more complicated too - what made you think it was different this time?
As for people posting things other than the truth on forums, I think that you will find that this is not confined to drinkers. As IRL, some people use an alter ego to play a part that they wish were true, rather than the reality. Personally, it doesn't bother me so much as long as they are helping, rather than trolling, and live in hope that they are helped by being exposed to the message.
So, what did you learn at your al-anon metting and when's the next one?
