HSV 2 Oral Transmission

I have been dating a girl for 8 weeks.  Four weekis into the relationship we decided both to get tested for STDs.  As expected my results were positve for HSV1 and negative for HSV2.  Her results came back positive for both HSV1 and HSV2. We have not have had intercourse.  Prior to getting tested I recieved unprotected oral sex from her.  

1) I understand that Oral HSV2 is rare; because she has HSV1 also does oral HSV2 become even more unlikely?
2) Is it possible for her to transmit HSV2 to me by performing oral sex on me?
