I know less about the false positive range in the test that you took (can you get me the brand?) but it is very low compared to the HSV 1 index value, so I would say, yes, get a western blot to be certain. You will want to know if there is a possibility for certain that you could infect him or anyone else in the future. You have a very strong HSV 1 result so there could be some cross reactivity with the HSV 2 test. If it were me, I would do it in a heartbeat. It sounds like you are starting anew life now, it would be good to know exactly what is going on herpes-wise.
