I think you handled it well, too! I have been (am currently in) your shoes. My AH refuses to be honest about his drinking and it's only when I catch him red-handed that he will confess. I could ask him "Did you drink last night?" He will say, "No. It's been 'x' days." I will show him a receipt I found and he will first start with, "Why were you looking through my wallet?!?!" and then confess. But he will ALWAYS say, "But I only made one drink with it and I felt bad and threw the rest out." Whatever. Like I am supposed to buy that when his first inclination was to lie. Trust your gut. My AH and I are separated right now and I am 99.9% certain we are headed for divorce.
