Men and women are both carriers. Since men cannot be tested for it, most sexually active men are carriers because they have no idea they have it unless there is a genital wart. Do not assume you infected her. If she wasn't a virgin when you met her, she could have gotten infected years ago. When sexually active people have sex, there should not be any finger pointing on who infected who. It is impossible to play detective with this virus.

During her recovery period, use condoms so she can recover quicker or give her a few months of no sex to recover. After that, you two can have all of the unsafe sex you want for the rest of your lives because you cannot re-infect each other. There is no ping pong effect. Stay monogamous with her forever and enjoy sex without any guilt.
