Has Mike given you any signs that he might be gay? Does he dress better than you, or give you fashion advice? <--- no these are not definate indications you are gay... but for some men, they are. Does he look at men walking down the street the same way you might? <---- much better indication.
Seriously, you don't have to have the "where is this going" talk. But maybe you should ask him what's going on, why he never holds your hand or tries to kiss you. He'll probably respond that
- [A]he only views you as a friend, and then it will be slightly akward and embarrassing for both of you. But then you'll know, and can proceed from there.
[B]say that until just now he only viewed you as a friend, but you've just opened his eyes to new possiblities.
[C]has wanted to on numerous occassions, but it never felt right, or he wasn't sure that you thought of him *that way*
[D]really likes you but his strict religious beliefs prevent any contact until marriage
[E]thought you knew that he's gay
It's probably best you find out now where he stands. No use getting your hopes up and then your heart broken when you can find out now and avoid a lot more pain. And if he
is into you, then you can start that part of your relationship now!
