advice cancer man help please

Hey guys, i need some help decoding a cancer man and whether or not there is a chance for us. here's the shortened version:
i'm a scorpio female and over 5 years ago i was dating a cancer guy. i completely fell in love with him, but i never told him this. we were only together for a few months before he broke up with me for reasons which were never really clear and we lost contact. i believe he knew that i had strong feelings for him but i never outright told him how much he meant to me or what kind of an affect he had on me. it has always been a mystery to me what happened for him to end our relationship. the explanations he gave were not clear, came down to i believe he didn't want to get involved/attached if we were going to end up separating (we were going away to school at the time although neither of us knew where yet and i had mentioned an interest in one out of town).
Anyway, turns out that recently he made contact with me and wanted to meet up. so we met up and had a great conversation, everything was natural as if we were old friends. we talked of many things, but i feel that i talked too much about my previous relationships, the ones i had after him. i'm worried that that pushed him away? i still care about him, very strongly and i never made it known to him. we haven't talked since our latest meeting but that was not long ago, and we both mentioned that we would like to get together again.
what kind of signs would show me that he possibly cares about me and is interested? i know that cancers are defensive and i don't think i made him feel safe or secure, can you help me figure out if this whole situation is defense at play or if he is not interested?
Thank you guys SOOOO much.

yeah i feel as if i made a big mistake concerning the fact that i went on about the other relationships. i noticed he looked strange during those conversations, looked down a lot and away. but i always think that if you care for someone you won't let things like that get in the way, although when someone had a person in their life whom they deeply cared about insecure me always think how can i compete. cancers are supposedly inseure, this is true?
i'm not the kind of person who pursues someone, but i get the sense that cancer's are not like that either. so someone is going to have to be more open. am i supposed to show him that he means something to me? am i supposed to get over my scorpio pride and make it clear to him how i feel in order for him to be able to let me know how he feels? that would be alright if i didn't feel that i had made a fool of myself over him back when we were first together. now i don't want to push him. what kind of signs can i look for? what kind of things do cancers do that reveal that they care for someone? ?>> yes he listened to me when we talked, he was interested, asked questions, but i think that he's just a nice person like that. i don't know if that necessarily means that i'm anyone special to him.

How do you know he's not already in a relationship with someone?

he's not.

Well, in that case you have nothing to loose by telling the person how you feel.

ha, i have my scorpio pride to lose. i'm not good at allowing myself to be vulnerable, especially if that person does not make me feel safe or has hurt me before.
but you're right. i have a feeling that it's going to come down to me putting that pride aside and just being honest, no matter what the outcome. at least then i'll know where we stand.
thanks.

Might as well try, who knows.. it might not turn out bad at all..

One more thing.. you asked about showing signs of interest.. I think it's enough the person sought you out and wanted to meet up again. And no matter how hard you put up a front to guard your feelings.. chances are that the person already knows.. cancers are no less perceptive than scorps. I say take a chance and see where it takes you.. you might not be disappointed.
