Everyone here pretty much hit it right.
Im sure this post wouldnt have been placed if no further communication had happened.
Wasnt cool on either side even though you were doing what you thought was the right thing.
For me once I make or accept an offer the deal is set in stone.
My word is all I have in this life. I have several normal males that "have been sold" a couple times in the last month. One person made a deal, didnt hear from him when he said he would contact me and then tried to contact me two weeks later. Sorry wont sell to him is the only response he got from me. I shelfed a whole day over less than $20 when there was a bunch of other stuff I could have been getting done.
Just remember to look at it from all sides when you start to make a deal because now its not just about you anymore.
