第五，有過婚史的男人，但女性未婚

　　A paper published in the European Journal of Operational Research in 2009 tracked 1,000 couples who were either married or in serious relationships over five years. Researchers found a ­previous divorce ­lessened the chances of a relationship surviving, although this was less marked when both partners had been divorced before.

　　和有婚史的男人在一起，他們容易再一次對婚姻做出不忠行為。專家還分析，如果男女雙方都有過婚史，那重新結合后相互做出不忠行為的可能性會稍微低些。

　　6. He's sex-obsessed

　　第六，性愛狂

　　One third of 1,468 men questioned admitted to viewing online pornography. According to Julia Cole, men who use internet porn on a ­regular basis are more likely to be unfaithful, as the habit can produce a deadening effect on emotions that can hurt ­relationships. Cole says: ‘Excessive use of chat lines, sex-texting and porn can leave someone numb to the emotional responses they would feel in a normal relationship.’

　　實驗中，1468個男人中有30%的人承認他們會在網上觀看性愛視頻，而專家稱，對于性行為有特殊癖好的男人比較危險。

　　7. He was privately (or religiously) ­educated

　　第七，有受過特殊的宗教教育

　　A survey by illicit encounters.com found almost one quarter of the site’s 500,000 members attended ­private schools. A further 15 per cent of members had attended religious schools.

　　在調查中，專家發現有過偷腥經驗的人中，有25%的或多或少接受過宗教教育，或曾進入過宗教學校。

　　8. He doesn't like your family or friends

　　第八，他對你的家人朋友無好感

　　Relate says men risk losing a close-knit support group, and not just their spouse, if they stray.

　　相信我，一個不愛你的家人和善待你朋友的男人，絕對不會善待你。

　　9. He's a social-networking enthusiast

　　第九，社交狂人

　　One law firm, Divorce Online, claimed almost one in five petitions they processed cited Facebook. ‘I am seeing an increasing number of people whose partners have been unfaithful through one of the social networking methods,’ says Julia Cole.

　　如果你的男人是一個“社交蝴蝶”，那么你真的要小心了。

　　10. He has a lower IQ than you

　　第十，他的情商很低，比你要低。

　　Earlier this year, a study by Dr Satoshi Kanazawa, an evolutionary psychologist from the London School of Economics and Political Science, revealed the smarter a man is, the less likely he is to cheat on his partner.

　　一個情商低的男人，很有可能做出很多不可思議的行為。做出以后，更容易被發現。
