I have a lot of girl friends, but never in my life have I asked someone to be friends LOL. I would say don't ever do that. It just sounds like some p*ssy shyt.
it just happens, and I never put people in an inflexible category. There's women that are my real friends, we have never slept together, but that's more on them. Some we have. Some we just kiss. But. she's a real friend, when I came back from a trip she picked me up and took me to my favorite market and IN N Out, that's my homie. And she has a boyfriend. But, that's a natural friendship. We didn't ever agree to be just friends.
That is Tik Tok shyt. I guess rom coms have pushed that for awhile too, but you don't really need to put people in such rigid categories. There's a great quote I heard in my marriage and family class in school, "relationships can always go forwards, they can never go backwards"
