cancer female and pisces/aries cusp man

The guy I'm seeing is a pisces aries cusp...I see a lot of both of these signs in him, which makes him so confusing. My natural instinct is to back away so I can get a better view, but I don't want him to think I don't like him either. Anyway...I have no idea how to deal with this kind of guy..and frankly I don't want to invest energy where there is no future. I also don't have his complete chart, and I will have to get that info out of him later on...as for me
