I'm a junior in high school, and my math teacher wants to be in a relationship with me?

You have every right to feel the way you do about this perverted teacher of yours, I don't see why the school has him working there still. If the school won't work with you on this situation, try and get some evidence that will put him in jail for ual harrment and try to keep your friends close to you at all times when around him or when walking home. Cause, not to scare you or anything, but it looks like this will get more and more intense as time progresses. I wish I could be of more help to you, if I were there I would beat him up and make it look an accident. Seriously though, stay safe, this world is not as safe as it used to be......
