Wow.... I guess I am really surprised at the responses so far. It seems like many are immediately jumping to the conclusion that the guy is an alcoholic, he is already blame shifting, ziggy should take a break from the relationship, etc...
I reread the first post a few times:
Recently he told me that he'd like to take a break from drinking and he's been drinking more since we started seeing each other.
To me this statement says nothing about Ziggys causing him to drink. It may just be timing that he has been drinking more, and only coincidental that Ziggy is around during that time.
This actually could be a healthy statement just being taken out of context. Personally I would have for once liked to hear my EXAG say that she was going to take a break from drinking vs. pretending it wasn't that bad or it was not even occurring.
