I'm in love with a 17 year old
Why do you love her?
She's such a lovely and cute girl
You shouldn't be in love with a minor. You should find someone closer to your age.
But I'm in love with her and I can't just leave her.
You might think you love her, but you're being predatory which will only harm her. If you truly care for this girl, you would leave her alone and focus on people your own age.
