I didn't invite my girlfriend to a party I went this New Year's Eve with my friends. Did I mess up?

She ended up staying home all night. But she didn't ask me if I wanted to spend New Years together either

This is something my girlfriend did to me. I just wanted to see i had a right to be hurt by what she did and if she should know it's a shitty thing to do. So far yes I should feel hurt and yes she should know
