1. don't be friends with a groomer
I don't care if you feel bad for distancing yourself from him. If he's purposefully making you feel bad? Don't feel bad. That's a way of keeping you close.. and that opens a door up for him to possibly groom you.
2. If you end up not distancing yourself, at least be mindful. He is not a good man. He is an adult, you are a child. He isn't supposed to interact with you like he does. He is a nazi, a racist, and a homophobe. If you see signs of him possibly going to groom you, let parentals or people you trust know, and drop contact immediately.
I do not like nazi sympathizers, so don't take this as pity. Take this as "Hey, I think you are a child in a concerning situation and I am choosing to offer advice."
Wether you choose to follow my advice or ignore it is your choice, but be careful and protect your peace. Be wary of manipulation tactics, and overall just be safe.
Tldr: dni with an adult groomer. Seek help if it gets dangerous
