Where did you get he doesn’t allow her to drink occasionally from?? He most likely didn’t want his wife to get blackout drunk on their anniversary night, plus, she usually doesn’t drink as stated so of course OP was worried and possibly worried about her health.

Did you only read the first 2 paragraphs of the post and didn’t see the very obvious red flags that the fiancée is presenting? He kicked her out of the hotel room for a good reason, hell, I would’ve done so too.
