I had a similar situation happen. A person I had been hooking up with (though I thought it was progressing into a relationship). I told him and he didn't leave, and came over to watch a movie and not have sex during my primary outbreak. For this I was thankful, but then it declined and I'll never know if it was due to H or if the relationship just wasn't working. I ultimately ended it because I felt it wasn't right regardless and it was also a shitty situation, it's been almost four months and I'm still upset by it though.
He claims he got tested and was negative, but I have a feeling they didn't test correctly, etc. etc. I guess I'll never know and it doesn't matter or make me see him differently, but I'm almost positive I got HSV1 genitally (and orally) from him because swab was positive, initial blood tests were negative, and six month blood tests showed low antibodies. (Like very low though, still confusing)
You never know, he could've tested positive and is just freaking out himself and not ready to talk about it. People react to things in such strange ways, and men tend to retract from situations that scare them (in both a good and bad way). I'm glad you don't blame him though, that's respectable and classy.
I agree with the eye opener thing–it's one of those things I just never thought would happen to me, really. I haven't told friends with the exception of a few, but I always think to myself, "if you only knew what could happen" when they're talking about sex and relationships.
