I got it and my b/f didn't get it from me after being with me for 9 months so he thinks it's a recent contraction because of all that the doctors told him. However, there is a chance that a persons immune system is different than the partner you're with. I swear on my life I haven't touched another soul. But him and i did got to Mexico for a week, I just learned that the bacteria can live in dairy (I'm not done asking doctors about that one). Did you ask her for her test results? And maybe you're right but please keep in mind there are way too many coincidences of people on this website who know where they have and haven't been. Just please think of it.
