Betrayed by My Girlfriend and Best Friend

So yeah, never thought I'd be posting here but man I need to get this off my

chest. Been with my girl for 3 years and was legit saving for a ring and everything.

Then her phone starts blowing up at 2AM like every night. She's all "it's just work stuff"

but like... at 2AM? Come on. I know everyone says don't go through

your partner's phone but whatever I did it anyway and holy crap my life just exploded right there.

Wasn't just one dude. FOUR. DIFFERENT. GUYS.

All these separate convos with pics I never wanna see again, them planning hookups,

and worst part? They were all joking about me. One was literally my best friend since
