feeling unattractive

There is a guy I know and we have hungout together in a group unteen times, I have really started to like him. I'm scared to even aproch him in that way because if i didn't have boobs or dressed like a girl I would look like a guy, because of my hair! Now I know that everyone who knows me or even lives in the same area as me know why I have short hair and I don't think he would judge me about it.... and anyone who is reading this the reason why I am feeling uncertain about my hair is because from February to April this year I was undergoing chemo therapy! But back to the point I'm scared to talk to any guy in a romantic way because I feel like they will reject me due to my hair, I feel as if they will think why would I want to date a girl who looks like a guy! So I want your opinions do you guys think I should go for it or not! I feel with some of your guys input I will maybe feel better about how I look! 😊
