I'm criticized for liking underage girls
Who was criticizing you for liking underage girls?
My family got annoyed with the fact that I'm dating a 13-year-old.
Going out with a 13-year old when you are a grown person is improper. Being with someone romantically when they are under the age of consent can get you arrested.
So what? I still want to be with her.
You don't care about being arrested? If you go to jail and they find out you were with underage girls, the inmates there will aim to hurt you non-stop.
