If your girlfriend and you both have HSV 2 then even if the strains are different (if that's even possible- I don't think it is) then she would have protection and you should not worry.
As far as the bathing goes, HSV 2 needs a lot of contact for transmission and so I doubt simply running a bath in the same general area would be a risk. Mostly you would shower and any if at all the virus would simply wash away. Generally she would only have to worry if there was direct contact with the susceptible areas...
If you are certain both you and your girlfriend only have HSV 2 and that this is what the outbreaks are then you should be fine.
yes you can have different types of hsv2 however they make no difference at all in the big picture. you won't get more ob's if you have more than 1 type of hsv2. outside of research, it makes no difference at all. You two can have sex even when you have ob's, it's not an issue.
your roommate is not at risk unless they are having sex with you. this is a sexually transmitted infection and not something you will transmit through sharing the same toilet or shower. Everyone in a household should have their own towel, washcloth, toothbrush, razor and body puff - because other very common germs are easily transmitted through sharing them.

Thanks for your imput. I fell better and learn a valuble lesson. I went from over cautious
to under. My fear and anxiety has cost me alot. It's not my well being that I worry about but those closest to me. I just don't want the guilt of passing it to someone else. I've been through that before and have mo desire to repeat. Thanks again
