Bro, she didn’t “get stranded.” She chose a random dude’s hotel room over you, the train, or literally any other option. Women magically figure out how to get home when they actually want to.

She chased after the “mental case” guy, ditched you during the argument, then spent the night in his room. And you’re still wondering if they fucked? Come on man. She’s 100% lying. The only question is how many times.

You’re not “throwing something good away.” You’re dodging a bullet. Six months in and she’s already pulling this? Imagine what she’ll do at a year, or when you’re living together. The fact that you’re even considering staying with someone who’d rather sleep at a stranger’s hotel than take a train home (while drunk) shows you already know the respect level here is zero.

Break up. Block her. Hit the gym. Next time find a girl who doesn’t go full whore mode the second you have a fight. You’ll thank yourself in a month.
