Is she wrong?

Last night my mom told me that I'm her and my dad's responsibility until I get married but I don't want to get married like it's not a priority for me and the way she said it made it seem like I'm some kind of property that has to remain untouched until I'm given to a man. Is it bad that I'm mad about this or do you think she meant it harmlessly? She was yelling at me about how I'm not allowed to hang out with guys.

BTW I'm 18
