Could it be as simple as the other guy is hotter than the boyfriend or is it more emotional?

Sometimes it could be more emotional, if you check my profile i made a similar question to yours, and you should check the answers, there are so many different opinions about this issue.
I think every woman just as every man has different reasons, different urges, different moral aspects, so it all depends on how somebody grew up... Not everyone is the same, i learned this from the answers of the question i made :)0THIS IS NOT RELEVANT ANYMORE

Dude all people cheat for different reasons so there is no clear cut reason. Though with girls it tippically that the other guy providing something the first guy not. It could be sex, emotional reasons or support, money, etc. But you never really know unless you ask that person but still tippically people who cheat will lie about who and why they cheated to so be careful.2THIS IS NOT RELEVANT ANYMORE
