Whoa, slow down. Your questions apparently are way ahead of the known facts. You don't describe why you believe you were infected by your current boyfriend and not sometime earlier, nor do you provide evidence that he actually is infected - or if he is, whether you caught HSV-2 from him or vice versa. It also would be good to know more about the specific kind of blood test you had and exactly what the results showed, to determine for sure whether you have HSV-2. Your partner needs a current HSV-2 blood test, then the two of you should go together to visit a health care provider knowledgeable about genital herpes, to interpret both your results and what, if anything, need be done to prevent transmission.
The following answers assume you in fact have HSV-2.
1) HSV-2 antibodies develop anywhere from 3 to 16 weeks after the infection is acquired. It is true that the large majority have positive tests after 12 weeks. However, in people who have never had symptoms and who test positive, most have been infected for several months or years. If that's the case, the odds are good that you will remain asymptomatic. Same for your partner, if it turns out he also is infected.
2) If you both have HSV-2, you need not worry about transmission between each other. People infected with either type of HSV are immune (or at least highly resistant) to new infection with the same type. This probably is especially so when both persons are sharing the same HSV-2 strain; partners do not "ping pong" genital herpes back and forth. In other words, you need not use condoms, dams, or any other precautions. But I stress that these things apply only if your partner also has HSV-2, which may not be the case. Testing is necessary.
I hope this helps. You might benefit from some additional background reading about genital herpes. Excellent information is available at www.cdc.gov/std, www.ashastd.org, www.metrokc.gov/health/apu/std, and www.westoverheights.com.

Most "routine" STD testing doesn't include tests for HSV-2. But if you are certain that the previous negative tests included HSV-2 in you and your partner, you might be able to work out who was infected first and who infected the other. I don't see that it matters and I'll leave that to you. With respect to prevention, my reply above applies.
If your sexual histories are accurate, then your partner had to come into your relationship infected with chlamydia. Or one of you has had other partners since then. In any case, chlamydia is a much more important health issue than herpes. I trust you both were treated. You both should be retested for it in 3-4 months.
Thanks you answered all my questions! Sorry I was not more clear, I was trying to condense. I had a blood test w/ a pap which includings HSV 1 & 2 screening, I was told that I tested positive for "HSV 2" & Chlamydia. My boyfriend was tested seperately and also tested positive for HSV 2 & Chlamydia.
The last pap & blood testing for STD's (including HSV 1/2) I had prior to this was in March 2006. My boyfriend and I became sexually active/involved in August 2007. Even before the March 2006 test, I was not sexually active from October 2003 until my boyfriend and I became intimate in August 2007. And I was tested twice between October 2003 and March 2006. So I knew I got it from my boyfriend because there was nobody else, and in the years prior to this happening I had been tested multiple times for this....
