What is the chances if you have hsv 1 but never had a cold soar.Ever. of giving someone hsv 2.?

I was married 15 years. I never had a cold soar ever. My Ex-wife got genital herpes HSV 2. She blames me for her getting them. I had a blood test done and it said I was positive for HSV 1 and Negative for HSV 2. What is the actual chances of me giving them to her? I have never had a cold soar. Maybe dry lips but that is all. I just need to know the percent of the change I gave them to her. we were together for 15 years. would this have not happened earlier if i gave them two her. The first doctor that told us together, she had Herpies said I could have given them to her. But the second doctor that gave me the blood test said no?
