How do you know if he's interested?

I seem to attract Cancer males and I'll be honest - they intrigue me. I find Cancer males to be the sexiest sign, although also the most frustrating and hard to understand. I've also been insanely and utterly heartbroken by Cancer males...yet it seems most of the men I meet are Cancers. How strange is that?

Anyway, how do you know when a Cancer male is interested - really, actually into you? I have a friend who has said he's not looking for more than friendship, yet he hugs me all the time and went out of his way to buy winter tires for me and change the brake light in my van. He's amazing but I'm not pushing.

I'm a Pisces, by the way.

He is interested I would say. See if he asks you out but for that you will need to show some interest in him YWIM.
