Confusion

A while ago, I asked about a situation in which my crush got a girlfriend. I did what you guys suggested, I tried to forget and went out with friends.

Well, a few days ago, I went round to a guy friends house. Whilst there, I noticed some strange feelings. Not like the ones I felt for my 'crush', but similair at the same time. If that makes sense.

And as you can tell from the title of this question, I am confused.

1. Do you think I may 'like' him?
2. What should I do about it?

Also, I'm sorry for all my questions being about boys. I know there are more important problems out there, but I really need to ask someone.
