Me and my mother argue about how much is too much to drink when we go to the pub. Has she got a point or is she exaggerating?

So every time we go out to the pub, she says to me we are gonna have 2-3 max snd then go home, but i always want to have a 4th glass because i’m having a great time. She calls me selfish for this and we end up arguing, then she ends up staying and having a 4th drink with me because she feels guilty.

Sometimes after we finish i ask her if we can grab a wine bottle on the way home she always expressed how she thinks i’m being excessive with my drinking by wanting to have a 4th glass of wine at the pub then buy one from the store on the way home.

This has happened a lot. She makes me feel like i’m on the verge of becoming an alcoholic and throws a fit and acts like i committed a crime.

Am i in the wrong? Should i cut back? I don’t get why it’s such a big deal to her.

P.S. I asked this question previously in a different way and people were basically making fun of me so I would appreciate genuine answers only. Many thanks.
