You can sue her, but you're unlikely to get specific performance unless there is no other equitable relief. However, to even get any sort of relief, you'd have to show that you have a contract, and I'm failing to see that. Even if you had a contract, what is your actual damage from the breach?
What was the item in question?
It's an antique Book case/Secretarial Desk. Not a ton of value, just wondering.
We do have an on record message thread where she did agree to sell it to me as quoted below.

"Hi, my wife Carol Wilson, contacted you about about this item yesterday and you had told her that you would be back on July 6th so we can look at it. We are very interested and would like to buy it. Could you please hold it for us? Jim and Carol Wilson. Thank you.

Yes, I will hold it for you. We won't get home until late on July 6th, so you are more than welcome to come look @ it on July 7. Thank you!

Thank you, I will check with you on the 7th about coming to look at it. I can bring cash or pay you with PayPal, whatever works best for you.

Good Morning! I own several antiques & have decided to have them appraised, including the secretary. I will let you know when this takes place (I'm hoping this week). Thank you in advance for your patience, I appreciate it. Happy Sunday!
