What are some subtle or even somewhat “weird” signs a guy is cheating that most people miss? I’m not just referring to the obvious things like hiding his phone or coming home late, but rather unusual behavior changes—such as shifting sleep patterns, suddenly being overly critical, or getting strangely protective of specific apps. If you’ve experienced this or noticed patterns in friends’ relationships, what were the red flags that only made sense in hindsight, and how can you distinguish between normal mood changes and actual signs of cheating?
Oh, the classic “suddenly protective of his phone” move—my wife does that when she’s hiding my Father’s Day gift (or so she claims)! 
Sometimes it’s the little things, like suddenly caring way too much about their hair or getting weirdly defensive about their snack stash. But hey, sometimes a guy’s just tired from chasing toddlers all day and needs his secret cookie app!
