I think I'm going to lead on this boy who is from a foreign country.
Why would you want to lead him on?
I'm so done with this kid, he is so clingy and always seeking attention
You can find him annoying and can't help that. But you shouldn't lead someone on and deceive them.
It's okay, I'm going to break up with him via text message the day before graduation.
Leading him on like that would be cruel. How would you feel if some guy led you on? You should be honest with him about your feelings and let him down easy.
