1. Improved appearance.
If your significant other suddenly starts exercising and eating healthier, that could be a sign that they are trying to appear more attractive to someone (possibly you, but possibly an affair partner). If Mr. Sweatpants-Are-Just-Fine-at-a-Party starts wearing slacks with matching socks and a fashionable shirt, or Ms. I-Can’t-Help-It-If-I-Smell-Like-Our-Son’s-Poopy-Diapers suddenly smells like Chanel No. 5, that may indicate an affair. Ditto for a new haircut and new underwear — especially if your significant other looks the same around you, but significantly better for work or certain social events.
2. Secretive phone or computer use.
Cheaters tend to use their phones and computers more frequently than before and to guard them as if their lives depend on it. If your partner’s phone and laptop never required a password before, and now they do, that’s not a good sign. If your partner suddenly starts deleting texts and clearing their browser history on a daily basis, that’s not a good sign. If your partner never relinquishes possession of their phone, even taking it into the bathroom when they shower, that’s not a good sign. If you ask to review your partner’s phone, and they say no, that’s also a problem. Honestly, what could possibly be there — other than information about your surprise birthday — that they would want to keep secret?
3. You can’t find them or reach them.
Couples that have been together for a while tend to know each other’s schedule.
If he or she is not where they are supposed to be, or if they are not doing what they tell you they are doing, it might be time to sit down and ask them what is going on.
When people are deceptive about their whereabouts or make excuses for why plans changed, things aren’t good.
If you can’t find them or reach them, there might be a reason for that and it’s because they don’t want you to.
4.They are angry and nervous around you
If your kind partner is suddenly angry and frustrated with you, know that it’s probably not you they are frustrated with.
Instead, they are projecting their own fears and insecurities on you.
It’s not always evident because some people change over time. Not everyone is who they first appeared to be and it does happen from time to time that one partner finds out the other partner is not who they said they were.
But if they have been in your life for a long time and are getting mad at you for things that don’t make sense, it could be a cover-up.
5 Their schedule is suddenly different.
If they have to take off for a few days for work and no, you can’t go too, something might be wrong.
If you’ve always traveled together and now they are saying you can’t come, cheating might be why.
If he or she is going with a work colleague and have a bunch of work meetings and you are not permitted to go because of “company rules”, there’s no company in the world that would say that.
Who has the right to stop you from tagging along, especially if you are paying your own way? Nobody. It’s fishy.
Psychologist Samuel Izuchukwu , says to Prevention that “someone who must ‘work late’ all of a sudden at times that go beyond a reasonable explanation may be cheating.”
If you’re seeing this symptom, as well as some of the others I mention in this article, it doesn’t necessarily mean your partner is cheating. However, you do need to start taking action to stop the degradation of your relationship.
