Aitah for getting annoyed at my girlfriends mom for joining us at every date night. We live together all three of us under one roof. We both work in food service her a (21f) assistant manager and me a (22m) assistant manager at different locations. Regardless in this economy date night at a decent restaurant is a little difficult to do. Maybe twice a month at most. And I always try to go all in with nothing cheaper than Olive Garden if I can help it. Lately ( last 5 months) her mother has been attending every single dinner. It’s always awkward and sparse conversation. I’m not sure if the anger just simmers over dinner or not. Moms in her 50’s no husband and no dating life. And is a rather heavy alcoholic. So most dinners with her and my girlfriend include mom drinking and pissing off my girlfriend off and than a heated arguments where I’m always looked at for the tiebreaker which I refuse to give because as I view most arguments as extremely childish and could’ve been solved by a few questions and answers. I don’t know what to do. It’s just we don’t have any common ground and when’ we have a decent conversation it’s usually about a movie I’ll never see on Apple TV and her mega pint of alcohol. She’ll ask us EVERYTIME where we are going, and proceed to invite herself. Am I wrong for wanting to exclude her.

She also helps us with a cheaper rent I think may have needed to be mentioned as well. She is a kind person overall just not when she drinks. We tried to get her to date someone but she convinced her kids(21f and 30m) don’t want her to date. But they’d love nothing more than to see her spending quality time with someone who can care about her in a romantic capacity.
