If you started taking acyclovir daily, the risk of infecting you partner who is HSV 2 negative is reduced by almost half - add condoms and the odds of infecting her are very low indeed.  If she was the giver of oral sex to you, she could still acquire HSV 2 orally, though that is uncommon because HSV 2 does not like the oral area.  But if she did acquire it orally, that would essentially vaccinate her against genital infection and it would rarely recur orally.  She could potentially infect other men, but because HSV 2 doesn't like the mouth, it infrequently recurs there and is infrequently shed from this area.  Swallowing semen does not increase the risk of contamination - semen is not a good carrier of virus.
