I can see why this is so confusing.
I do want to clarify something - when you say your wife had the Western Blot, do you mean she had it cultured? A Western Blot is a blood test, not a culture. If she has hsv1, the WB test would have been positive, so I'm guessing you meant she had the sore cultured and that came back negative?
Also, to confirm, since you and your wife have been monogamous for the last 7 years, I'd assume both of you had partners prior to that?
If you had a cold sore as a kid, that's hsv1. The problem with our testing is that hsv1 IgG tests - and make sure your tests are IgG - miss a full 30% of infections.
If you did have cold sores, that means you've had hsv1 orally for a long time, and the test is just missing it. Your Bell's Palsy might have been caused by the hsv1, but that can be caused by other things, too.
Canker sores aren't hsv1.
There is no difference in your hsv2 tests - I've had hsv2 for 20 years. I could test today and get a 15.9 and tomorrow get a 13.4 and the following day, get a 14.7. It means nothing. It could mean that the lab tech who read the report cut the test off when it was clearly a positive, that there was what we call "background noise" on the test, etc. Also, no one ever gets a true 0.00, so if they reported your negative with an actual value, it might have read .072 or .68 and those aren't any different either.
Your wife can get her hsv2 IgG test at 12 weeks. It takes up to 12 weeks to develop antibodies. If it's negative then, and you want more confirmation of what you both have, and I can see why you might, your doctors can order the Western Blot test. It's more expensive, but it's the most accurate test there is.
Now, assuming for this that you have hsv2, but not hsv1, and your wife has hsv1 but not hsv2. What does this mean for your sex life?
For you, not much. It is very unlikely that you'd get hsv1 after getting hsv2. The hsv2 antibodies offer strong protection against hsv1.
Transmitting hsv2 to your wife is a little different, though.
Transmission rates from a male to a female, assuming sex 2-3x a week, in a monogamous relationship, the stats are:
Just avoiding sex during an outbreak - about 10% a year
Adding daily suppressive meds OR using condoms - about 5% a year
Using both meds AND condoms - about 2-3% a year.
Transmitting hsv2 via oral sex to someone's mouth can happen, but it's uncommon, and unless you had an outbreak, I wouldn't worry about it.
