Are vegans 'high maintenance'?

I've been told I'm high maintenance because I'm a vegan. I don't get why because I'm really independent when I shop and Make my own food, I don't rely on other people to do it for me. I also don't push other people to go vegan. So, is it true that because I'm a vegan guys will avoid dating me once they find out?
