What is Herpes exactly?

Ok, I know this is a stupid question. Yes I googled it.

So, all my life I pretty much thought Herpes 1 was a cold sore you get on your mouth when you are sick and that it goes away. I thought Herpes 2 was a STI that can be easily treated and goes away after medication.

I just saw a group here on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> especially for Herpes. I clicked it not knowing why an extra group was made for herpes until I saw some posts.

People writing about being scared for having it forever, talking about their kids getting it, talking about how many people don't even know they have it.. omg.

Oh. My.

So you mean to say all people I saw with a cold sore that had herpes actually had a pretty harsh virus? Damn. How does it not go away? How do people Not know they have it? I don't get it. Please explain.
