How To Know If A Cancer Guy Likes You

Idk I just get a feeling that he does.
He's really quiet and shy. I'm the type that is not that all cheerful but I try to be. So when I see quiet people, I just talk to them right away.
Whenever I see him, I greet him but now I realize I might be giving him the special treatment, I hope he doesn't notice 😄
He always seem to be sad about something and I give him advice from time to time.
Maybe its just my hunch but maybe he likes me back? I might like him. Honestly, I find him interesting. Alot of Earth guys always give up after I say "No" or "I don't want to"
He's the kind that will ask "Why?" maybe that's why I like him, because he's sensitive.
Or maybe I just want to have someone listen to my problems too? Like a friend?
He's really gloomy but he looks different when he smiles, he was glowing too.

Hard to say with the lacking information. Cancers- or at least me- have been known to make people think they like someone more than a friend. This has happened to me at least three times now in the last year. I cherish my friendships and look for good trusting friends. Not to say that he doesn't like you but with just saying that he talks and smiles and listens to your stories sound like a friend.

There's an element of their whole hart involved in this.

I am involved with a cancer man with Mars in Leo and a Gemini Venus and Moon.

He;s a cancer in a lot of ways, but that Leo moon makes him forthright.

He told me the day we met that he liked me. He then called me for four hours and pretty much within 2 days ways saying he wanted to have my babies and go all caveman on me.

I am sure some cancers can be more shy and careful though.

Why not just ask him?
