I'll keep this short and sweet. My best friend is a guy. He's quite laidback, quiet, political and very bright to the point that most people avoid him like the plague. We have a very close friendship and I can talk to him about pretty much anything knowing I'll get comfort or reassurance about opinions and choices. We've known each other about five months or so now. I used to fancy him quite a bit and he gave off a lot of mixed signals, he'd do stuff like lean in to talk to me and make it intense, hug me lingeringly and stuff. I told him straight out that I liked him and where was our friendship going - he told me he loved our friendship but it was going no further than that and was really serious and sort of careful about that - he got that it bothered me a little.
We're fairly affectionate - in that he's affectionate. I'm used to him putting his arm around me when we watch movies, play with my hair, rub my arm and stuff but lately he's got more affectionate than ever. Our hands were linked one day and we were just sitting in silence when he lifted my hand and kissed my fingertips for a second - when I lean forward, he puts his hand on my back, he'll push up my teeshirt sleeve when we're sitting to draw circles on my bare arm. I dunno quite how to handle it - he was categorical that he didn't fancy me and he's not gay. What do I do? What on earth is up with him?
