Is she with friends having fun, or is she drunk-flirting with random dudes in clubs/bars or worse? What if she has a history of being irresponsible when drinking and tends to blackout and engage in dangerous behaviors?
Yeah, she can do whatever she wants, but if that includes things that could kill her or otherwise cause significant harm to herself, there might be reason for concern.
The only time I would ever get mad at any girl for drinking is if she was on medication that says alcohol is not a good idea, if she's a recovering alcoholic, or if she's pregnant.
Same applies for guys really, except the pregnancy part. Any time you're getting sloppy, that should be a wake up call that you need to alter your behavior when drinking. It's funny for about 5 minutes, and then you're a liability to those around you for the rest of the night - especially a SO.
It doesn't bother me at all, so long as she doesn't get so drunk that she pukes.
What is she doing while being drunk without me around is what determines my response.I don't care nor do any of our friends, male or female.
