I like my taken guy best friend

We’ve known each other for a little over a year and I actually wouldn’t call us best friends but we’re pretty good friends. He has a gf who’s across the country for college so it’s a long distance relationship. Every time we hang out he’s always playfully bantering with me. Like he’ll block me from walking, or jokingly tease me, and he once tried to tickle my feet. I always think maybe he just acts like that with everyone, but every guy that ever liked me before, acted like he does. I know I should stop hanging out with him but I really appreciate our friendship. He’s also in my friend group so I couldn’t get away from him without canceling all my friends. I’m not trying to steal him away from his gf, they seem sweet together but he’s just really charming and almost all girls fall for him. I guess I just needed to rant.
