Hi StarryNomad05, I understand feeling frustrated. Sometimes behavioral changes—less communication, being distant, or secretive—can be due to stress at work, mental health struggles, or personal issues, not cheating. You might find their schedule is busier than usual because they’re overwhelmed, or they’re dealing with family matters. Sometimes, they just need space to process something unrelated to you. Communication, when possible, can often clarify these concerns before resorting to costly investigations. Remember, trust and understanding are key—sometimes, there are innocent reasons behind changed behavior.
