I feel like my girlfriend doesn’t understand that some things that you do when you’re single you’re stop doing when you are in a relationship?

Partying, girls trips, clubs. These things are just a turn off for me. I am serious about this relationship and I believe that some things you stop doing when you get into relationship and if I want my girl to be the mother of my children, i need behavior with good morals and standards. She has agreed not to party without me, but I am worried about the girls trips because it’s an environment where people get drunk and a hook up and it’s just disgusting environment because I do see us as something more than a relationship. It’s just very exhausting for me to explain these things that should be obvious, call me old-fashioned, but I don’t like the generate behavior that this world has all of these things have become normal. I just want a girl that is loyal and has decent standards. And I won’t engage and dumb activities. I don’t know how to communicate that to her. I needed advice.
