Different is a good thing, it's what makes us better than the plain people. Plain people are dull = boring, no fun. Life is for fun and happiness
Don't do silly things to hurt yourself. Don't ever change, stay who you are inside and out. If people don't like it, screw them. I know my family get involved, I wish they would keep out of it. But go for what makes you happy.
And I'm sorry to know. But if he did that, then he's an idiot who never truly loved you. It was life, not meant to be. It will hurt you, but you will find someone who loves you in time. Stay hopeful, and be yourself; then you will be happy in time.
