Cancer man/sagi woman?

I have a friend who's a sagittarius and she met this guy who's a cancer. does anyone has experience in sagi girl/cancer guy relationship?

ja ja my girlfriend who is a sag just married a cancer last year ! They are so in love. He often tells her he loves her crazy way of loving, they are too cute. Im not sure how compability between the signs work but they are a great couple.

My Sag dad was with a Cancer woman for about 16 years but just like he left my mom for her, she left him for another man.

Thanks for the input guys. i have a feeling that cancer man want to be there for the drama of it. she's a bit needy, manipulative and dramatic. so, it might be either a good or bad match. she just got out from a bad and very controlling relationship with a guy who was 10 years younger and made her life a miserable hell. just want to get some perspective on her new situation.
