I really like this guy at work and I think he doesn't like me in the same way!
I really, really like him and I want to go out with him
What should I do?

If you don't ask you'll never no!
BUT do you think its agood idea to go out with somebody from work?
Because if you break up you'll have to see him everyday
But its up to you weather to ask or not could you see him everyday
If he dumped you? You would feel hurt every time you seen him if you like him that much
If you dumped him? You would feel guilty when you seen him

Well, A couple of weeks ago, I accidentally sent him a text saying that I really liked him! And ever since he's been funny around me! Does this mean that he's uncomfortable around me?

How about friendship? How about simple civil "get to know you" behavior for awhile? All this "ooo, I like him" stuff is really just silliness. Be a friend, be friendly, don't be creepy.

And this is WORK, careful you don't get out of hand in the workplace. Bad news.
