how would you know if your boyfriend/girlfriend is cheating on you?

girls have woman instinct...so if our boyfriend will cheat us we will know...but some women deny to their own selves that their boy is cheating to save the relationship...thats what you call martyr girlfriends..

Well, I think social behaviour patterns tend to change a little. For some, it also depends on the impact of thenew relationship. For instance, time spent together deteriorates. There is some possibility of irritability of one by the other even over very flimsy grounds or trivial matters. Your partner will call less often than they usually do. You can also try and notice te "attachment"factor. you find that your partner will somehow distance from you little by little. They might stop holding hands, not intentionally, but rather "automatically" since it is something that is in them, and they might fail to sort of "correct"the situation. Others will even call you by the name of the person that they are cheating you on!

Intuition, test, facts. But we must not mess the paranoia and the jelousy with the intuition. We just need to be more carefull to the signs in the daily life, to see if there is something different...

If they have cell phone try and get a look at a call log when they're not around if you suspect something. A lot of times a cheater will delete their call log but it leaves a blank space when there should be 10 last calls. At least that's how it used to be back a few years. The new phones maybe not, but most people aren't smart enough to delete their call logs. Also look for mysterious names. A guy won't put a girl's real name in his phone, he'll usually disguise it to be slick.

People who cheat make up a lot of excuses for not finding the time to be with you. They always got something else to do.All of a sudden they say they're been busy ; when before they always had time to spend with you. They come over and then make up an excuse for having to leave early.Their whole pattern changes from being with you to the " cheating pattern ". You call them and they are on the phone. Say they will call you back; but they don't. You don't hear from them for weeks.You call them ; they don't pick up because they don't want to talk to you.When they do come around you; there will be a difference in the way they act.There's that gut feeling that you just know when they are cheating.If you ask them ; they jump on the defense.
