Should I confess to my crush that I like him?

You should always confess to your crush and ASAP before the lose intrest or find somebody else. If it's obvious they like you back then go for it! If you don't really know give it a try. If they don't like you accept politley- don't burst into tears or hate them for it. That would be akward. Remember there are so many people out there probably just like your crush. If not you can still meet someone esle awesome!
