A Hardheaded Seller

Ok so about a month ago I came across a seller negotiated a deal that brought in $2600 a month which i thought would be good for my buyers because its in his target area we negotiated the earnest money and terms and now he wont give me a contract unless he speaks with my buyers. A month later goes by i ask him wheres the contracts he said he will send but he keeps insisting that he speaks with my buyers first and im like yea right, like i would give you the opportunity to go around me and steal my buyers and close a deal without me he knows just as much i do that nothing in the real estate world will be exchanged without anything in writing. I dont know you like that. LOL. Now hes saying its because he hasnt gotten the earnest money and a transaction cant be complete without it. Im said brotha who are you fooling, no money will ever ever be exchanged without a contract signed ever...its business 101 and he needs to brush up on his real estate and hell never complete a transaction acting like this and it will make HIM look bad not me. How do i know youre not some scammer a contract says AT LEAST you have product. What you expect to take my buyers money and I have no product? No way in hell am i gonna allow you to make me lool bad nor allow you to go around me. Then he says it doesn't make sense to send blank contracts. SIGH....I said it makes perfect sense earnest money wont be exchanged without a contract neither will my buyers info. Were all putting our names on the contract for it to be signed so that it can be sent to title and escrow opened. He needs to brush up on real estate and ask his attorney or get a new one because i dont know who the ones hes been dealing with told him this....deep breath....i told him there are plenty more properties to buy if he wont send me a contract otherwise im done explaining and to see who the fool will be who would send you money without anything in writing or gaurenteed. So my question is it time to walk or wait to see if hell send the contracts. Yes i told him all of that, i wont allow myself to be taken advantage of i may be young but im not stupid. LOL....what are your thoughts on this? Sorry for the long post....
