If you choose do not use a lawyer, I would ask your realtor to write up the acceptance of the counter offer. It will have to be in writing at some point, the sooner the better. Until both sides have signed an accepted contract, it is not binding. IF this is the only property you want, I would not walk, but bide my time until the bitter end.
I always suggest to both my buyers and sellers that they have an attorney represent them for closing in any and all real estate transactions, both residential and commercial.
Attorneys usually step in right after papers are signed during the due diligence period. Sometimes, in complicated deals, it's best to have the attorned review your offer/paperwork before it's sent to the other side.
When you have a real estate attorney representing you that is aware of the dates on the contract for specific performance, i.e., answering you back in writing, due diligence, etc., they will make sure to be involved in the day to day process and that you will be answered in a timely fashion!
Here's the attorney I use in Broward county for my closings:

Harold S. Bofshever and Carlos J. Reyes
