My gf booked Santa for a night I'm due to go away with the lads

A guy got in touch with Niall and Sho with a big dilemma"My girlfriend is not talking to me. I want to know what you make of this.I got invited months ago to a Christmas night with my college mates. We are going to Kilkenny at the weekend. She knew about this.On Friday she came home and said that she had booked for the three of us - myself, her and my daughter to go see Santa on Saturday - when I am in Kilkenny.I said I can't go because of the lads night and she lost the plot. She called me a selfish ****. She said I am putting a night with the lads over my own daughter."
