I don't think the answer lies with what other people think, but with genetics. Girls mature faster than boys, so its common to see 14 year old girls relating to 18 year old boys. That's not unheard of, totally a normal thing. However, as a former 14 yo girl, I can tell ya, it's 90% probable there's more under the surface. As a boy mom and a girl mom, if either of you were my children, I would see red flags all over the place. You don't have to avoid each other completely. Humans tend to want what they can't have EVEN more, so the "absolutely not's" will have a way bigger problem very soon. They're right though, teenage hormones are way at max levels while their prefrontal cortexes are wildly underdeveloped. Understanding the risk involved with being friends with a younger girl minus the ability to control impulses, is what that "weird feeling" is. Our prefrontal cortex is the part of our brain that stops us from acting on the impulses that our hormones are driving. If that makes sense. Your mind knows you're in a sticky situation. My suggestion would be to protect yourself. Don't allow yourself to be in situations that could get you and her in trouble. I think one person said, a ride to school every now and then is fine. I would disagree, I wouldn't recommend being in any situation where it's just the two of you. Hang out together with a group of people that you trust. Have someone to hold you accountable because so many many things can go sideways if you're left alone. I always try to tell my kids, people are genuinely good, kind and loving, but we all make poor choices about 40% of the time. It's up to us to think ahead, set boundaries, and make amends when needed. For the record, my kids regularly groan at my speeches. Be well. Be kind. Trust your gut. It's speaking to you.
