I'd tell her not to take dating advice from a bunch of teenagers on Reddit. Then I'd tell her that any guy who wants her time should treat her at least as well as I do. I would tell her no matter what happens I'm a phone call away, day or night I'll be there with no judgement. I would remind her that most things we try we are bad at is at the beginning, and dating isn't any different. I would say don't fall in love with a guy who doesn't share your values and your vision. I would tell her not to stay in a relationship because she thinks it's good for the guy (or girl) if it isn't good for her. And I would tell her that you need more than love to make things work. Don't settle down early. When you first start dating it's all going to seem shiny and exciting. Take this time to learn what you need in a relationship, and remember to always expect respect.
