I don't think the growth you burned off has anything to do with herpes. I am a bit impressed (and a bit appalled) by your self-surgery, but you seem to have achieved removal. (I wouldn't risk it again, though.)
If your partner came down with herpes after having sex with you, she might have caught it from you, or maybe not--maybe she had recurrent herpes before she met you. A first-time occurrence is usually associated with severe pain and swelling and swollen glands. Did she have these?
In any case, if you never had obvious signs of herpes, you should have a blood test for herpes 2. If you're negative, you can be pretty sure that you didn't give herpes to her. On the other hand, she might have given it to you, if it turns out that she had it before and was shedding.
Bottom line: check your herpes test, and don't cauterize yourself.
Take care.
