first off, i'm very sorry to hear that your husband had to be so selfish...it doesn't seem very possible for people to stay committed to just one person anymore these days
to answer your question, yes, it is possible that he has passed genital warts on to you. warts kind of have a mind of their own...a person can be carrying a strand (there are about 60 or 70 different types of strands) and not even know it because they won't get any warts...they kinda just show up whenever they want to. the thing that sucks about testing for hpv on men is that if the man doesn't have any visible signs of warts, then there is no other way to find out if he has hpv. because it is a virus that hides out in skin cells, not blood, doctors cannot do a dna test on a man, and because there are no pap smear-like tests for men, there is no way to test the skin cells inside of a male penis. so, it is definetly possible that your husband is carrying a strand of warts, passed it onto you, and not even know it because they aren't showing up on him (right now).
if i were you, i would get a pap smear done and find out for sure...it's also very possible that those aren't warts (what else they might be, i don't know because i don't know what they look like)...it's possible they may be nothing at all. just get checked out by a doctor as soon as you can to be sure. good luck.
