Looks like you have already asked yourself the key questions, like "do i see this person as a life time partner", "is this a serious relationship", "what do i want from life" etc.
Basically in my personal opinion it all boils down to whether you feel you couldn't live without him, he is the one, you dont want anybody else, you are willing to catch herpes if it comes down to it. If you are sure that you don't want anybody else, then by all means, still get educated on this topic and simply learn ways of possibly not catching it.
If you are unsure about how you feel about him and the future then DO NOT HAVE SEX. As the other poster said, you can still pass the virus on whilst using condoms. This unfortunately is something the authorities concerned do not stress enough in literature and in sex education at schools. Everybody thinks condoms are the modern day life savers when it comes to sex, but they are far from that.
I caught my herpes virus using condoms and i wish i had found this site sooner. In my case though, i wanted to be with him and i would rather have him and the herpes. I simply couldn't have imagined life without him.
There is a rather long, but helpful, thread much further down the page (or could be on page 2 by now) called Happy Couples. You ought to have a read of this thread whether you stay with this guy or not. Actually you ought to get your boy friend to read that thread too. It is very difficult having this virus and finding somebody who wants you regardless, so he might have found it difficult telling you in the first place and rejections are difficult for most people to take, so perhaps the Happy Couples thread will give both of you a more positive outlook regarding this virus and relationships.
Good luck to both of you and congratulations on not ditching him on the spot and instead looking for answers. More people should be like you
