I'm going to call out my gf on a bad gift and tell her what I want
Do you not like the gift or something?
I'm not happy with her gift, she spent way too much on it
Sometimes people get it wrong when they give a gift but it is not right to be mean when receiving a gift. You should appreciate the thought.
I'm going to tell her it's not good enough.
That's some seriously entitled behavior you're displaying. You should appreciative, not an ingrate.
