In all out honesty, I have a best "guy" friend whom i've never been attracted to and never even thought of hitting on. He is not into me at all. He and I have even shared a bed together (WHEN I WAS NOT MARRIED) and we didnt even think to touch eachother. He is not an ugly guy, its just he is like a brother to me.
We are strictly friends. It is possible if two people go into it knowing its just platonic. We've been friends for over 6 yrs. My husband knows him and is not threatened at all. His lady knows me and is also not threatened. I don't call him at all hours of the night, I don't disrespect her in that way or him. We're just friends.
HOWEVER...
I do think that if you find someone whom you were friends with first and it turns into love..it could be the type of love that actually lasts.
