Positive For HSV2. Painful Bump In Lower Labia. Suggestion?

hi' I need help. I month ago I tested positive for hsv2 ,by the swab test, and 2 wks later blood ,and read the same as the swab. a yr and 1/2 ago I had a painful bump appear on the lower labia groin area. made an apt right away,doc said nothing to worry about use hot compress, I asked for the heck of it to swab test but he did not. several mths later it came back, he again said don't worry, I wanted a swab test but again he had no concern. I had it again ,and than just this past month I went again this time I demanded a test, I seen a diff doc, and know iam told this. iam married ,never missed around on my husband, my ex was tested over a yr ago hes neg. is this from my husband hes going for a blood test next wk. I was last with my ex in 2009,2011 he tested neg. iam I correct to say that I got this from my husband and was I recently infected when I first had that bump, I never had anything before. if it was in me why would my ex be neg. I do not know what to think I cant think anymore. I don't know if my husband messed around in the marriage,had it before ,or just did not tell me.my doctors also failed me, I should have known this 1&1/2yrs ago, it just seems to me if I was the carrier my ex would be positive we were together 8yrs.iam assuming my husband will be positive. he says he never cheated but how could all of a sudden this be. can you please give me some kind of advise. thank you ,,
