So this girl ive been talking to wants to hang out and drink tomorrow night, but she still has a boyfriend.

I think she is trying to use me to help her break up with her boyfriend.

I told her we would have a blast. I then told my dad about it and he told me not to have sex with her tomorrow because she could decide the next day that she still wants to be with her boyfriend and file a false rape claim. I live in missouri and am not familiar with the laws.

If it reaches that point should i sleep with her?
