My husband and I had multiple conversations where he asked if he could give the sake to his father, his cousin, or his friends, and I said a strict no every single time. Not vaguely, not jokingly, very clearly. He knew it was sentimental and partially a souvenir. He also refused to drink it the one time I opened it because he had a headache, so I had about 20 ml and left the rest untouched.
Fast forward to three days ago: I'm away from home, and he has friends over after a pub night. I didn't even consider that he would touch the sake or the wine because we've had the "don't share this" conversation a million times.
The next day, I ask him where the sake is. He casually tells me he shared the sake and the unopened wine with his friends, and they finished everything.
I was stunned. Angry. Disappointed. All of it. He then says he "forgot" that I told him not to give it to anyone. Then adds that he "doesn't remember unimportant stuff." Bear in mind, I had even given him a bottle of whisky specifically meant for his friends after I returned from my travel.
When I confronted him about the sake and wine, he flipped it and said "Don't let it spoil our relationship" and suggested I see a counselor.
AITA for being this upset over something he claims is "not a big deal," even though I'd told him explicitly and repeatedly not to touch it? I'm unable to process the fact that my husband casually crossed a major boundary and is nonchalant about it.
Edit: Husband and his friends are not alcoholics. He rarely indulges.
Second edit: He said, "Don't let it spoil our relationship,", not "throwing away the relationship…" Sincere apologies.
