Hey Sam, first off—big hugs. That gut-knot feeling sucks, and you’re not alone. Changes in behavior (like being secretive with their phone or dodging questions) can be red flags, but they’re not proof. Sometimes it’s stress, not cheating. The best move? Honest convo. Ask how they’re feeling, and share your worries. Trust your instincts, but don’t jump to conclusions without real talk. You got this!
