<human>: original: 

Went onto Jen's fb account last night and found a shit load more pictures on a secret group page. i don't want to get into details of what was on there but i now know that she definitely cheated on me and almost every girl there in a relationship cheated on their boyfriends in one way or another (even the fucking bride to be). I feel fucking sick.

I flipped at her last night. cheating is one thing, but she straight-up lied about it to my face. Every single person there knew exactly what was going on and lied to me as well. I feel like a complete idiot and everyone who said i was being stupid yesterday was 100% correct.

We're going to talk again tonight now we've both calmed down but I'm not sure this thing is salvageable based on how ape-shit I went last night and what she has done. An honest mistake could be forgiven but I have a hard time thinking about forgiving a liar. I want to get past this with her. i know people will say this is utter BS idea but i still love her and i don't want to let this situation end us.

I need help reddit. Sorry for being a moany idiot but is there any way to salvage this? Does counselling work? How do i make sure this shit doesn't happen again? and wtf do I do about the psycho girl who has copies of all these photos? should I tell the groom that his bride was at it as well?

Can you give me a shortened version of the text?
<bot>: she definitely cheated and i don't know what to do. I need to fix this relationship. I don't want to end something so good over something as shitty as this.
