Welcome to the STD forum. I'll try to help.
Most likely you do not have HSV-2. It is very common for the HSV-2 test to give a weakly positive result when someone has a strongly positive HSV-1 result, as you do. The inhibition test is supposed to sort this out, and it does raise the chance you actually are infected with HSV-2. However, it also is not a perfect test. Additional evidence against HSV-2 is your boyfriend's negative test; it is more likely that his test is the reliable one and yours is false. And you cannot catch genital herpes from shared towels, bathrooms, etc. On top of all that, it is almost impossible that you could have caught HSV-2 while taking valacyclovir (Valtrex) for your oral herpes.
The way to sort this out is to have another HSV-2 blood test using an entirely different test method. One possibility is the BiokitUSA test, which is done in a doctor's office in 20 minutes. (If your doctor doesn't usually do that test, s/he still can order a test kit from his office supply company.) Or you could have your doctor send a blood specimen to the University of Washington clinical laboratory in Seattle for a Western blot test. WB is the ultimate gold standard for HSV antibody testing. If either the Biokit or WB is negative for HSV-2, you can be sure you are not infected. Here is the link to another thread that discusses these things in a bit more detail:

Valacyclovir does not alter the test results and certainly does not result in false positive HSV-2 tests. Your eye problem has nothing to do with any of this.
Bottom line: Have the additional tests -- but in the meantime, you can be pretty sure you don't have HSV-2. This definitely should not be a cause of panic or alarm!
I hope this helps. Best wishes-- HHH, MD
