I have a slightly different opinion - did you pour it out because you wanted him to not drink, or did you pour it out because it was really bothering you to see it in the fridge/cupboard/bathroom sink/wherever? If your motive was the latter, I don't think it was a "crazy" thing to do. You shouldn't have to have your living space invaded by booze if you don't want it. If your AH doesn't want his alcohol dumped, he'll have to find somewhere to put it where it's not in your face.
