The volume of alc my partner drinks really upsets me, not his actions. Warranted or out of line?

I have a complicated relationship w drinking as does my partner. Large consumption’s of alcohol in 1 sitting trigger me, due to family history and partners past behavior. I have been in therapy working on control around his drinking, but I still really struggle with the volume he consumes. It’s 2 bottles of wine a weekend. And I just found 375ML of tequila hidden in the trash. So 1 bottle of wine and 375ML in 1 night. He hid the tequila from me as he knows I don’t like him drinking liquor. thThat is A LOT of alcohol to drink in one night, but if he’s safe, non disruptive and just buzzed do I have a right to be mad about the volume he’s consuming? Honest feedback please.
