You get to know what they do every day and how they act throughout the day. Most people have a routine and they stick with this routine. They’ve changed their everyday behavior.Just be sure they’re not really busy or distracted with other stressful endeavors. Even though people cheat, they still feel guilty about it and therefore, they’ll avoid you in order to feel less guilty about the affair. If you feel as though you’re being pushed away from them and they’re putting distance between you, they could be cheating. Many people even give their new person a different name so you won’t get suspicious. If they start talking about this new friend in their life but won’t really give you a name or allow you to meet them, it could be their new lover. If your partner is suddenly being very vague about their whereabouts, it’s possible they’re cheating.
You usually know if they’re going to the store, to a friends, or off to the bar. Most significant others will give specific details about what they’re doing and when. They’re being vague about where they’re going.However, if you call their office and they’re not there when they said they’d be, it’s a good possibility they’re using “working late” as a way for you to not be suspicious if they’re off with the other person. Now, this could be a completely legitimate reason for them staying longer at work. If your partner is hiding their phone from you whenever they get a message or a call, it’s a sign they’re cheating.
Since we communicate the most through our phones, it’s only likely that if they’re cheating, they’ll be texting the other person and even calling them.
