So she is hosting a home birthday party where I'll be the only boy. The party will end at around 10pm and I'll stay over to sleep there. We will sleep together in her room. Her father will get home when the party ends and will sleep in another room. Gf said that we won't do anything tomorrow. I don't know why she said that, maybe she is afraid that her father will hear us or catch us? Anyways should I still escalate and not listen to what she sais as is adviced here or respect what she said since we're at her place?
