Major Trade problems

So i offered a trade to this guy which included me getting Moss and Deangelo Williams. He counters with just Williams saying that this was more even. He never resend the trade he offered and we continue trying to negotiate for Moss. He says he wants MJD for Moss and tell him no way. He still hasn't withdrawn the Williams trade, and i didn't reject thinking in my mind that if i can't get Moss i'll still take the Williams trade. I accept it once we can't get a deal done for Moss and now he wants to cancel it, because all of our trade talks had ceased on Moss for MJD. Who is right in this? Should the trade go through or be canceled?
