I still recommend you getting copies of the pathology reports. Atypia is not normal. It literally means "not typical." At the age of 50 (and this is my opinion), the doctors should not be approaching atypical paps with a "wait and watch", especially since you have not had a new sexual partner in that many years. They need to figure out what is going on.
An exception, if you have an infection or had some sort of trauma to your cervix (and intercourse can cause an atypical reading) or are taking certain medicine. Those can cause an atypical reading. With that, though, they should give you more medical terms than just "atypia." Is it ASUS? AGUS? HSIL? There needs to be something else besides atypia.
I hope you are feeling ok, otherwise.
