Hey Nonas I need some advice. So a little while ago I started chatting with a moid from 4chan, not typically something I do but at the time I wanted to continue the conversation off of the board. He had the beginnings typical misogynistic views, but after talking with me for a couple weeks I sort of saved him from sliding down the redpill slope (admittedly I gave a little bit of a savior complex).
He eventually told me that he was 17 years old. I was 22 at the time, which did concern me a little bit but I never intended to have anything beyond an online friendship. We continued talking for a few months and started to become good friends as I convinced him away from redpill garbage and discussed all sorts of things. As time went on I discovered a sweet personality underneath his moid vaneer.
We met up in my city a little after his 18th birthday (we live roughly 2 and a half hours apart by drive) and had a little informal date. In real life he turned out to be rather cute looks-wise and had the same sweet, almost puppydogish personality as online. We had a couple more meetups after that which brings us up to now. He is going to be going to college studying physics in my city, and the campus is 20 minutes away from my apartment. He wants to take our relationship further and actually start dating.
This is a thought that's been lingering in the back of my mind, but given our age gap and ages when we met, am I sorta in the wrong here ethically? I know legally I'm fine, but it could sort of look like I "groomed" him, not that the term is very accurate because I never manipulated him or made him or even suggested doing anything that would make him uncomfortable like moids do to girls. I like him and he's heads and shoulders above most other moids at this point, but the situation does feel a bit iffy and I'm thinking about ending it before our relationship gets more serious. Do any other nonas have experience dating younger guys and how did it turn out?
