What should i do, if i like somebody, but they are dating someone else
Well, there really isn't any one definitive answer. If they're already dating, you'll have to wait it out either way. Like I said, school relationships don't last very long. Once their relationship ends, you should soon after tell him/her how you feel. If you don't, you run the risk of them finding someone else. Plus, what have you got to lose? However, if their relationship does somehow end up lasting a long period of time, you may just want to move on. The human brain is amazing at adapting to situations and moving on from trauma, it just takes a bit of time.
