I am a 40 year old married SD. My long-term SB(25) of 2 years has disclosed recently that she tested HSV1 positive. We were not exclusive and she don't know whom she got it from.
I always used condoms but we never used condoms for oral sex and I gave her oral too.

This puts me in a difficult situation since its hard to determine when she got infected and how many times we met since it shows on tests only after several weeks. I am aware of HSV1 being very common but I am scared of bringing this home.

I am thinking of breaking up with her. What are your thoughts on this?
