I Had Unprotected Sex With A Woman I Have Been

I had unprotected sex with a woman I have been dating about 4 days ago. She began to experience vaginal discomfort and was diagnosed with a UTI. She continued to have issues so she went to ER and discovered she had herpes. She said she has not had sex for about 3 years. I have had 3 partners (all in long term... At least 8 month relationships, having unprotected sex regularly, in the last 3 years)... None of whom have had any symptoms... Nor had I experienced any symptoms until yesterday...small blister/sores in the groin area. I got tested today but have not received results back yet, but am assuming I am also positive. Is There anyway to know who gave it to whom and how long one of us may have carried it?
