awwwww, hugs for the sammie!! It's funny, if you post this in the alkie section, people may ask you if your jealous, but the friends and family people might tell you to leave her=)
When my husband and I split, we had too many problems to overcome. We had both been drunks. One of my problems I couldn't get past, was that every time he got THAT drunk, he repulsed me. Straight up turn off!
Anyway, you have to decide if it is a threat to your sobriety, or if you can deal with episodes like this occasionally.
I personally would have a partner reserve those kinds of nights for when I didn't have to see them at all, have them stay at a friends (or I would), and maybe offer to pay for the cab.
