What are the signs that a person is being cheated on?

I have been cheated on and have been the cheater.
The cheater was as sweet as pie but men are not good at cheating, no offense. He was too friendly with the girl, didn't set boundaries to their friendship, openly flirted and was a bad liar. I snooped thru his things and got all the evidence I needed. (Not condoning that behavior).

When I was the cheater I was very slick (not condoning this). I was only found out because the guy I was with had trust issues and was following me, checking my cell phone, etc. And I wound up admitting to cheating.

I have always thought that if you think you're being cheated on, you probably are. And even if you're not, if you don't trust your partner enough to feel that s/he is being loyal, and you feel there's reason to doubt them, you probably shouldn't be with them in the first place.

When they act funny when their phone rings and don't talk in front of you for certain calls or when their phone is off whenever they're around you. when their hair smells different than a shampoo they're using. when you find underwear that aren't yours. they act distant and start an argument when you ask what's wrong. you call them at work when they're supposed to be there, and find out it's their day off. find hair that doesn't belong to you on their bed and shirt. when a person randomly knocks on the door or window when you make a surprise visit and they don't let you answer, they sit there in fear and tell you it's a crazy ex. yeah I've been cheated on a lot and sadly, these are just a small percentages of the give aways.

I'm a fairly observant person so I was able to notice subtle changes in his personality over a period of time
he'd turn away from a random kiss
he didn't reach for my hand when we walked together
he stopped letting me answer his phone or even hold it. That worried me
we were going on fewer dates
i really started to suspect things is when
he'd run out on our dates
he spent a lot of time on his phone but not on the phone with me
he was 'always at work' or 'so busy'
the biggest problem was the sex it was still earth shatteringly amazing for both of us and that kept me from figuring things out
but eventually I figured it out

I have never cheated and never been cheated on (to my knowledge anyway) but I would think the signs might include - acting distant, not returning phone calls, initiating arguments on a regular basis . I would think you would know when something doesn't feel right, when your boyfriend or girlfriend just isn't acting the same towards you anymore .

I've been cheated on many times :-(. It can be where you walk in on the girl screwing another guy. To you can tell signs. Such as spending less time with you, hanging out with "a friend" all the time, less I love yous, fewer phone calls, loss in interest of sex, not wanting to cuddle, anything that's out of the ordinary that is not a cause of her period. You also just ask. But I'm very sorry if your being cheated on :-(. Let me know if you need someone to talk to. I may be young but I'm good to talk to.

Consider your understanding of your partners day. Time to work and time to play. How much play time are you getting? Is your play time becoming less and less?

Yes I have been cheated on, not many times but yes.

Mine was given away by a pair of black brief underwear that I found in the washer NOT MINE. This was a pretty easy giveaway.

If you share RENT or something that might hurt you more if you break up like a car payment, CHECK PHONE RECORDS. Texting is almost always the best bet!
