There are reports of virgins who get HPV but doctors think its from hand to genital sex. However the more likely source was your fiance. 90% of all people who get it clear the virus within 6-24 months. Half do it in 6 months. To increase the odds of clearing it, eat healthy, exercise often, don't smoke cigs, cut down on booze, take lots of vitamins (C, Zinc, A, E, B complex with folic acid, etc), get plenty of rest and reduce stress. A strong immune system speeds the recovery. You should assume your fiance has it too and since he cannot be tested, he should boost his immune system too.
