any advise? 😔 not a cheating post*

UPDATE*** well I confronted him and he told me it wasn't a big deal that 30 years from now me being raped wouldn't matter... pretty sure that will always fucking matter to me... and he was mad at me for snooping around. He said that she doesn't know our names and couldn't pick me out in a crowd so him telling her was not an issue. 
I'm seriously so hurt by all this. We just had our baby not even a month ago though and I just don't have the energy to fight about it. 
ORIGINAL POST****
Okay, let me start by saying that I know snooping is wrong and my BF is truly wonderful BUT I had seen he was messaging a girl from one of his online games, so on a day I was feeling particularly insecure I decided to look at the messages between them. I found that he had shared pictures of himself (nothing inappropriate) and pictures of me (that his friend complimented)... this online friend does not know his real name so it is sort of anonymous chatting but he did share our pictures and for that reason I feel upset that he also shared with her that we previously had an abortion... 
I was extremely hurt by this but did not say anything. Now last night I saw over his shoulder he was messaging this girl again so I looked at their messages today while he was at work and found that he had told this girl that I was raped in high school... WTF...
So now this stranger has seen my pictures and knows literally the most personal and unpleasant things I have ever been through. I am so hurt he told this girl these things about me but I can't confront him about it bc I found these things by snooping. I truly do not know what to do. 😞 it just isn't right to be sharing such private things about me with someone I don't know (he doesn't even really know her) and also providing her with my photos.
