I'm sorry she cheated and lied, but that doesn't change the medical aspects of this.
Your herpes tests are conclusive. You do not have hsv2. Hsv1 doesn't offer any protection against type 2, and it wouldn't make hsv2 hide. At 34 weeks, if you had it, it would show on an IgG test. You don't need to retest. You do not have hsv2.
If the biopsy showed bacteria, trust that.
It's actually not surprising that you didn't get hsv2 from your ex. Since you're male and she's female, if all you did was avoid sex during an outbreak, there'd only be a 4-5% chance per year that you'd get it from her.
I don't know if your ex lied from the beginning, or just found out in the middle of the relationship, but it doesn't matter to you now, medically. You didn't get it from her, and that's all that matters.
When you start dating again, have an STD talk at the beginning of the relationship - before you have sex. Test for STDs together, and share your results. This way you'll know for sure who has what, and it's a good way to start building trust. You can make an informed decision based on the results.
For now, you can start putting this behind you. :)
