Why if he asked? just curious. You're talking to a girl who asked her fiancé instead of the other way around. Though maybe I'm just impatient.

If he likes someone else, well then there's really not much you can do but wait. Tread carefully: you don't want to set off any land mines in the process and ruin any friendships. No one likes drama. But if you can, I think you should totally go for him.

Also don't wait for guys, they never notice. They can be silly like that, and all the anxiety you feel they feel too and are just as likely to be stopped by it. So if you think he likes you but is too afraid to ask, be bold and ask for him.
