I’m a little confused here. Why are you taking acyclovir and who would prescribe acyclovir for an uninfected person? There is no benefit for an uninfected person to taking acyclovir. It is he who should be taking the medicine daily, not you! Perhaps I’m not reading this correctly.
As for the possibility of you having oral herpes: it is possible yes, but taking antiviral medicine daily can prolong greatly the time to antibody development which is what the test is looking for. when you say that you got two sores on your lip, can you describe them more fully? have you ever in your life had a cold sore on your lip? What is your HSV 1 test value?
