It will only live for a few minutes. The reason lipstick and lip balm like chapstick can spread hsv1 is because most times you see someone use it and then ask to borrow it.you also rub it into the lips and that's exactly what the virus needs.
In your case again is zero risk as like I said the virus is very fragile and won't live long once exposed.
There are no Dr's on these forums. The moderators and fleetwood20 are just people with a great deal of knowledge on the subject. Again you had no risk . If she had an open cold sore at the time (which would be obvious) your chances would still be very very small. You do not have to worry about either you or your boyfriend.
and I also don't need to worry about autoinoculation or anything along those lines since there was no risk of transmission? or about passing to my BF anywhere?
Even if she was having an outbreak? Also, not to be rude, but what are your credentials on this site? I see doctors commenting on things but also random people.
Zero risk. You can move on without concern.
