<human>: Can you give me a shortened version of the text?

So some background really fast.

We live together after moving to a new country to start school. It made sense for us to move in as opposed to trying to find two separate places etc.

We are rely on each other pretty strongly for financial support and are around each other constantly, for this reason all of her friends are my friends and vice versa.

Now I was snooping while she was out of town (it's wrong, I know) and found [*linked in comments*] among her messages (her name is grayed out, her friend's is blacked out). They're talking about a mutual male friend of theirs that I have only met briefly.

It doesn't say anything outright but it's damn suspicious and at this point the little trust I did have in her is gone. I want to know how to take my next steps though. I can't kick her out, I can only move out myself but that will take sometime, I have no friends to live with too. 

We are both in a private language school and have to be for the next 6 months, I can try to transfer but it would be complicated and expensive. Basically I can't avoid seeing her or these friends for the next six months.

As upset as I am right now the rational part of me knows that I want to make this a calm as possible, I want us to separate and I want to continue my education and I want to keep highschool dramatics out if this.

What do I do though? Confront her? Just break up? Wait until I find a place then leave? 

Some hard advice would be appreciated. Thank you all.
<bot>: Pretty sure my girlfriend is cheating/planning to cheat. I don't trust her and want out but we live together, what's the best way?
