My Boyfriend's Fling...

AHHH. So my boyfriend has this friend, we will call her Brittany. Brittany has been in a relationship for two years. She's an aspiring model and she's the kind of girl who literally picks at food. She's sooooo skinny!

Well, the four of us hang sometimes. It's kind of nice having a couple as friends so we don't have to pay full attention to our friends, but we can comfortably just be a couple.

Anyway, I found out that my boyfriend and Brittany had a fling before her and her boyfriend started dating... The messages are still saved on their Snapchat messages!!! Him saying she's "not the run of the mill girl" that she's "gorgeous like a girl next door type". He even said she looked "fucking hot" in her costume and "no future boyfriend will ever care about her as much as he does". There's messages of him to other guys still saved saying "he cares about her so deeply" and they cuddled and he was just giving it time... I feel pathetic. This is a girl I've let him hang out with while I was at work. A girl that he sees everyday still. I wish he would have warned me.

I told him I saw the messages... (I didn't snoop, at first... their messages were open and I saw one so I kept snooping...) He was angry that I wanted him to back up from her a bit and that I wanted him to ask her to unsave them. He said it was a long time ago and nothing really happened and it'd be embarrassing to ask... finally he said he agreed if it were the other way around, he would be upset and he had her unsave them.

But cmon. She's a model and all that stuff he said... I know they never had sex because he was a virgin. And they didn't do anything sexual. But I don't know if they kissed... and he says it was no big deal, but now I keep seeing more flirtatious stuff about her from back then. I know it's all old and a long time ago, but I don't want to be friends with this girl. Why would they have still been saved anyway?

Her and her boyfriend are always rude, selfish, and they constantly ditch us or blow us off. I've been telling him I hate how they treat us for months, but now I dislike her even more. But he still sees her at school (college) and they still hangout and talk there so I don't know. This is bothering me a lot... I know it is just jealously, but is it rightfully so? I wouldn't have kept a friendship like that, especially at this point in our relationship.

I just don't think I can be around her without replaying all of those messages in my head over and over and over... What do I do??
