Should I ask her if she is interested?

Dude don't be ALL wack and chicken just go and ask her and talk to her about. Things will turn wayyyyyyyyyyyyyyyyy better that

You should let her know for sure that you're interested. Lay the flirting on HEAVY and see how she responds (note: fun flirting not sleazy flirting). If she's into flirting with you then she's probably into you.

The amount of awkwardness depends on how much regular interaction there is between you two and what kind of people you are. There was a potentially awkward situation with this guy at work but it actually made us better friends then we were before because instead of shyly avoiding one another after the fact we kinda made an effort to let each other know that things were cool. He's a really great guy, the timing was just wrong for me.
So, unless she's a jerk there's no reason why you shouldn't be able to maintain your friendship. And who knows, maybe down the road things may work out for you. ;-)

Hey. Communicate with her (better call than email), you don't need to be blunt about it. If you manage to not create an over-serious atmosphere things will be less awkward if she is not interested. But I guess if your gut feel told you she was interested, this is probably true. She might be shy, just as you ;).

I think that you should just tell her how you feel about her. If you don't make the first move than she probably thinks that you're not interested in her either. If you don't ask her she might loose interest (if she likes you) and figure that things aren't going 2 go anywhere. So just tell her how you feel and if she doesn't like you then it may be a little awkward at first but things will smooth out after a couple of days/weeks. If you really really really like this girl then don't let your interest die out, sure it might be hard to be courageous but this life is about taking risks and if we don't take risks then how are we going 2 experience things.

Great girls are always shy around the ones they are interested in. So good luck trying to get her to let you know how she feels first. If she's one of those brazen chicks then more than likely she isn't commitment oriented.

Now since you knwo she isn't going to tell you first that she's interested in you (if she is) then you have to let her know in a modest way. You don't want to go overboard cause that my scare her off.

Best thing you can do is say something simple at the end of the date ONLY something like "Hey by the way. I like hanging out with you. " Give her a light kiss and say goodnight.
