Wow! I am in awe of how self-assured you sound in the post. Like the others who have posted here, I agree that you did an excellent job calmly expressing your concerns and boundaries. Yay!
I'm
really impressed that you refused to police his drinking. (I fell into that trap with my STBXAH. When it didn't work, it was just one more reason he had to point the blame for his drinking elsewhere.)
I'm sorry that you're bummed about the conversation. I always wished the conversations with my STBXAH went differently too. I find it so hard not to expect rational thinking from him....
You did great! Hang in there!
