Well, a Lyme specific band like 23 - 25 that is IND should be treated like it's a positive. Remember, Lyme lowers the immune function, so it can't always produce enough antibodies for a 'fully positive' result. And (sorry) if you had been infected at the beginning of the relationship, your body has been infected for 3 months - more than enough time to lower the immune function, as there is a very small window of time that these tests actually work. Too soon and the body hasn't had enough time, wait a few weeks, and it's too late as the body has already been too compromised to be able to produce enough antibodies.
I wanted to agree with Girlie also that a negative co-infection test isn't reliable either. The co-infection testing never is - because Lyme lowers the immune function and they are looking for antibodies for those tests as well.
And, as Jrpsf said, the choice to use herbs or pharma abx is a very personal one. Go with what your heart/gut say to do for you. If that one doesn't seem to be working, you can always add in the other at a later date.
