Elli,
You will be "over for good" well that would be tough to deal with because of all his charm and house decorating skills. Seriously, ask yourself how many more years or episodes like this do you want to deal with. Has his drinking been less and behavior much better as compared to years past? If not, you may one day look back at today and refer to them as the good old days. It is hard to offer firm or even general advice because so much is left out. Have you been married long and are thier kids? Are you 72 years old or 27?
Safety is the prime concern at all times. It does sound like he is a nasty drunk, and by and large those are the ones you want to avoid. It sounds like you need an exit plan, unless you find this situation tolerable. People on this board will give you solid advice. However, it will be varied advice. ONLY YOU know how bad or dangerous this situation is. ONLY YOU knows if there is something to be saved by staying, or saved by leaving. ONLY YOU, Knew what level of danger he is or could become.
Curious, when you got in the car with this drunk to all get out guy-who drove? He had driven himself there showing total lack of concern and sfety to everyone on the road. I just am wondering if you got the same level of concern......peace
