I'm dating a 12 year old girl.
This sounds like a situation that could end up with serious legal trouble for you. Why are you dating someone that is underage?
She is a good cook and she has a responsible nature.
It's illegal to date underage people. I would strongly suggest that you end this relationship immediately, and possibly look for a mental health counselor.
See. This is why I never should have told you.
It's pretty normal for people to have a negative reaction when they about someone dating someone underage. It's illegal and wrong to date someone that young. It's not healthy for a child that young to be in a relationship with an adult.
