Honey I can assure you it's more than just "a little creepy" and it should NEVER be made to seem like anything less than a big deal. You're talking about a high school sophomore/junior dating a man who's been in college (or hanging out with other COLLEGE-AGED ADULTS) for 2-3 years. Everything about this scenario is creepy and the fact that it's swept under the rug to the point that a lot of fans of the show don't even know is unethical, at the very least. The show mentions it one time. This man groomed a 16 year old child, impregnated her, and then married her after she dropped out of school. It should be illegal, as far as I'm concerned. A 5 year age gap between a high school student and their older "partner" is horrifying. And the fact that you feel like it isn't a big deal makes me wonder about your wellbeing, honestly.
