Scenario: Two people are in a 5-month casual but exclusive relationship and have discussed getting more serious. The girl has a drunken one-night stand with a guy she doesn't care about and ends up telling her dude a couple of weeks later only because she finds out the one-night stand might have an STD, so she informs him so he can get tested, too. A few weeks later, the girl finds out her dude has been seeing someone else the entire time he's been with her, despite his many assurances that he hasn't.
Is one lie worse than the other or are they equally bad?
They both cheated. His cheating involved emotions, while her's didn't. Is one party more wrong than the other, or are they equally wrong?
I kind of want some validation, but I'm also genuinely curious to know what people think about this. My friend disagreed with my point of view, so I'm wondering how others see this.
