Dating a cancer man

If you’re into signs I need your advice. I’m an Aries woman and I really like this cancer man. We agreed on a friends w/ benefits relationship but I want more. I know our signs aren’t that compatible but I really like him. He likes me too but we’re in our early twenties and he’s just not ready for that commitment. He told me he’s been hurt a few times so it turned him cold hearted but I think he has potential. 😬 How can a cancer man fall for an Aries woman? If you’re an Aries have you ever dated a cancer man?
