Can having Chicken Pox as a child cause me to test positive for HSV 2 Genital Herpes?

Hi,
I am wondering if my recent positive test for Genital Herpes 2, can be positive if I had Chicken Pox as a child?  In other words is there a chance that the HSV test could be incorrect?  If there is a possibility, is there another test that I can do that would offer me deffinitive proof either way? I also tested positive for HSV 1.  I was tested Oct 22,09 and I found out from my Dr. on Oct 27,09.
My husband has HSV 1 Oral Herpes and he says he's had it for years.  Is it possible to contract HSV 2 Genital Herpes from someone who has HSV 1 Oral Herpes?

He admitted he had sex with a prostitute 2 months ago around August 13,09 but swears to me that he and I have not had sex since then. We were and are in counseling. I believe we have had sex.  His HSV 2 test came back Negative. He had the test 6 days or so after sex with the Prostitute.  He also swears that he used a condom.  
We've been married for 10 years and have been having sex for 11 years.  I KNOW I've been faithful to him. Any help in answering my questions is much appreciated.  I am devastated!
