Hi Shady,
My friend DB Lady gave you an excellent answer (thumb up). You started your question: ".... there is that guy I know....." If you really know him (that means know him in depth) than you can make your own judgement if he is good or bad and you shouldn't bother what other say. If you ment you only know his name / face than better know him more ("learn" about him) before you decide. Only if he is a good / honest guy give him a chance. The way he treated you is not very promising (that's an understatment). Yes, I have a feeling / hunch he likes you very much.
Best regards,
