<human>: Short back story -

* We have been together for almost a year.

* She was tested for regular STDs at the start of our relationship. She had chlamydia and got treated.

* She lives with her EX (5-yr relationship), they are not romantic and he is rarely home. I know she isn't cheating. But they own a home.

Few weeks ago I was snooping because something wasn't right, in the beginning of the relationship my doctor asked me to ask her how many partners she had in the last year or so. She told me one, her long term relationship with her EX. However, I just thought this was a lie and one night curiosity got the best of me and I snooped on her texts and emails. I confronted her and she told me she did have a relationship with someone between me and her EX. I didn't pry further, just knew there were probably more. 

However, while snooping I found texts from her EX saying that he had got tested and had herpes. He has since had other partners so I didn't think much of it and asked my GF to get tested. That was March 8th and the texts were from 2 weeks prior. She has still not been tested and its almost been a month since i asked. It's bothering me to the point where I may break it off with her. It's honestly not the fact that she MAY have it, its that shes scared to get tested.

Basically i just need advice on how to proceed from here.

Can you condense the text into three sentences or less?
<bot>: Snooped on GF's phone. Found texts from two weeks before my snooping that her EX has the herpes. I asked her to get tested on March 8th, still not tested.
