Hi and welcome to PC! I'm sorry that you're going through a difficult time right now. It sounds like you're making excuses for his behavior for him. He doesn't sound like a very good catch to me. If he gave you herpes without warning you ahead of time that this was a possibility, in my eyes that makes him lower than pond scum and says a lot about his moral character. There is no shame in having herpes, it is very common and easily controlled these days, but the reason (I think) that it's so common is because people that have it aren't honest about it.

It's very upsetting when a relationship ends, but it sounds like you're much better off without him.
