Welcome to the STD forum. I'll try to help.
Thanks for making the effort to research this before asking the question. You found accurate information; indeed there is a fair chance your HSV-2 result is falsely positive, and Western blot testing is a good way to sort it out. This has been discussed many times and in great detail on this forum. Below is the link to one thread that explains it; you can find others by using the search function and entering such terms as "herpes diagnosis", "HSV blood test", etc.

The main take-home message is that even though results of 1.1 and higher are technically positive, many results are false positive unless the result is over 3.5 This is a problem mostly in people with positive HSV-1 result, like yours. With an HSV-2 value of 2.64, there's probably a 50:50 chance it is false. The Western blot is the gold standard to sort this out. However, there is a less expensive alternative. If you can find a provider who does the BiokitUSA test (done in the clinic in 20 minutes), a negative result will mean your current one is false, and a positive would confirm you do indeed have HSV-2. That said, when you combine the cost of a (new?) clinic visit plus the test, perhaps WB alone will be no more costly. It's usually around $150.
If your result indeed is true, there is no justification for the notion that it would "ruin my future", and of course being in the Army won't make any difference. The military doesn't routinely test people for HSV and even if they did, it would make no difference to them. But cross this bridge if you come to it. Feel free to return to report your follow-up WB or BiokitUSA test result.
