It sounds like your warts have gone into dormancy and she may have gotten the warts from someone other than you as they are very common (to my understanding). No one will ver know unfortunately
No medication treatment of wart exist even today. The body immune system would eventually eliminate the hpv infection. In term of the virus, your body would create antibodies that will fight it and stop replicating.
Straight copy and paste from CDC about HPV.
HPV types are often referred to as “low-risk” (wart-causing) or “high-risk” (cancer-causing), based on whether they put a person at risk for cancer. In 90% of cases, the body’s immune system clears the HPV infection naturally within two years. This is true of both high-risk and low-risk types.
In most cases, the body fights off HPV naturally and the infected cells then go back to normal.
Sometimes, low-risk types of HPV can cause visible changes that take the form of genital warts.
