Hi JT,

Is this the first outbreak for your girlfriend?

Herpes can lay dormant for many years before some stressful situation brings
on the first outbreak.  And, so you should know, a person can have herpes
and never have an outbreak.  That means you could have given it to her.
Before you start thinking about infidelity, you should have a herpes test
done on yourself.  That way, you'll know what you already have, or don't
have.

Now, it's really easy to pass on type 1.  It's possible your girlfriend got
it from a peck from an aunt, or a friend, or a child, etc.

Also, it would be a good idea for your girlfriend to find out if she really
has herpes.  Did you do your diagnosis based on your research?  Or did a
doctor do the diagnosing.  It's unusual for herpes to be inside the mouth,
so I would want to make sure it is actually herpes that she has.

Your girlfriend can pass herpes on to you at anytime--whether she is showing
symptoms or not.  This is why you should find out if you already have
it--that way, you won't have to worry.  There are medications out there she
can take which will cut down the chances of her passing it on to you, if you
actually negative for herpes.

Take care,
ar
