how to proceed

My fiancee was diagnosed with genital warts today by her obgyn, 1 month before our wedding.  I do not have any warts as far as I can tell.  We have been having unprotected sex for maybe a year now and she thinks she probably has had the warts for at least that long.  She told me they were just much smaller last year and that the obgyn dismissed them at her checkup last year.  They are testing to make sure she doesn't have any of the high risk types.  I was not sexually active before her for over a year and have never had any warts.  I am not considering leaving her over this as I understand it to be common.  My questions are:  

1)  Is it possible I gave her hpv and just never had warts even though it was at least a year since I had sex?
2)  Should I be concerned about catching hpv at this point and is there anything I should do?
3)  My biggest concern is that since I didn't have warts if I did give it to her and her warts go away (she was given aldara) will I reinfect her?
4) Is this something that she will have to deal with for the rest of her life?(the obgyn told her they may keep coming back, especially if she gets pregnant)
5)  Last I read it is worse in immunocompromised people, if it is life long does it case problems later in life?

Thank You
