There is no such thing as a crystal ball when it comes to knowing whether or not your new guy (or girl) will cheat on you. However, there are some tell-tale signs that indicate (s)he is more likely to cheat than the average person.
Most cheaters are unlikely to sacrifice their wants to satisfy someone else's. If your guy doesn't see the value in respecting other people's wishes, he won't respect yours in the long run. Does he wait forever before he returns his friends calls, if he returns them at all? Is he constantly on the outs with any of his siblings? Are his co-workers all crazy and he is the only sane one in his office, according to him?
If your guy does not treat those around him well, you can bet he will start treating you the same way once the newness of your relationship fades. He disrespects those around him because he doesn't see the value of a good relationship. Loyalty is not his thing. And that makes him more likely to cheat.
Whenever your girl has a free moment (with or without you), she is on facebook or her blackberry checking messages. Checking her messages with you there is not only just plain rude, but it may also be an indication you are not enough for her. She may be craving constant reassurance from other people that she is popular and well-liked. Her need to feel wanted may be more important than staying loyal to you, so she could use cheating as a way to further satisfy her need.
If your guy is relentlessly doubting your feelings for him, often asking you to reassure him of your feelings, that is also a sign of trouble. It may seem flattering at first. Who doesn't love to be needed? But it could indicate he is low on self-esteem. Just like over-using social networking, needing continual reassurance from you has the same repercussions. He may use cheating as a way to get more reassurance that he is a desirable, great guy.
When it comes to dating, many people are looking for monogamous relationships and are honest in their intentions. However, if you are having doubts about the person you are dating, look for these subtle clues. They may help you avoid future heartache.
