you say a woman needs to ask her man or potential mate several important questions. explain that to me. >> remember, not all men are born to be cheaters. there are plenty that are not. first of all, look at his history of relationships. does he have a bunch of angry exes? has he fooled around before? there's a good chance he will do it to you, too? how much guilt did he feel? you know men feel less guilt than women in general? >> can i say something here, if you have a pen and a piece of paper, start writing this stuff down. fair warning. continue. >> many people -- their behavior is shaped through how much guilt they feel. if you're watching your guy and he seems to not have any problem bending the rules at work, even if it might hurt a co-worker, well, it means he's not going to feeling a lot of compassion and empathy and guilt for you. you want him to take pieces of you into that mental compartment and not have an affair. how old is he? did you know that one study on guilt shows men feel the least amount of guilt in their 40s and
