<human>: We've been together for one year. Went through a lot. She dated an asshole of a guy before me. Her ex didn't treat her well, lowered her self-esteem by saying she's ugly, won't hold hands with her on public and was basically just his fuck toy. Those issues sank deep inside her and it's what's keeping her from improving herself even when I'm here. We encounter something and it boils down to her self esteem issues by that past relationship.

Fast forward to a couple of days ago and she's been experiencing pain in her lower pelvic area. A quick google search shows it might be her ovaries and one of the symptoms might be and STD. This paranoia that lasted until today eventually led her to tell me that she acquired an STD from her ex. She went to an OB before but never really got a diagnosis and was just prescribed strong antibiotics and said was "cleared" of it. She had herself checked for HIV/AIDs before we even went out.

I'm hurt. Really hurt. Not because I might be infected but because she didn't tell me this and might not even have any plans if this recent pain of hers didn't occur. She said she had no intention of hiding it from me. Adding that she was so stupid for letting it happen. It's been hours now and I haven't replied to her messages. What do I do? I really love her but with this incident, some trust issues have been made.

Could you distill the essence of the text into 1-3 sentences?
<bot>: SO never mentioned she acquired an STD from her ex and it really hurts and I don't know how to approach the issue.
