reason of extramarital affairs

I think every situation is different,no two marriages are ever the same.thre could be any number of reasons why people be it husband or wife have extra marital affairs.here are a few examples: Example A: One of the kids get killed and the wife is so deep in their own grief they dont see that their partner is suffering too.Instead of reaching out to her husband all the wife does is push him further away.The poor man needs someone to be there for him and help him to grieve as well so he will look for love else where.Can you really blame him? Example B:The husband is a bartender and to keep a good clientel he flirts a little for business sake.The women who frequent the bar love him,he has a good persoality,tells jokes and makes everyone feel special.This man loves his wife and would not cheat on her,but she doesnt trust him and is always accusing him of cheating even though he is not.Eventually he will get tired of her always accusing and decide that he might as well do it if she already thinks he is anyway. Example C:The husband is a businessman who is often away more than he is at home.The wife gets lonely and is tired of always feeling that way.So she decides to fnd someon who will appreciate her company and ends up having an affair.

i don't honestly know what the reason is i mean i know that everyone has their own beliefs and things like that and i know that people can make mistakes and things like that too...but i've always been against cheating i mean i know that i would never cheat in any way whenever i have a girlfriend or a wife because obviously that person really does trust me and i don't want to destroy that trust and hurt that person by cheating on them..and even if they didn't find out..i would always know about it and i really wouldn't be able to live with myself after going out and doing something like that...so i don't honestly know why people cheat...

well just my opinion..when there is NO LOVE NO TRUST NO UNDERSTANDING.....then the doors are open to extramarital affairs...all 3 should be balanced even if one is amiss then the sanctity of marriage is at stake.

I know one lady I work with who has extramarital affairs... Way I understand her situation is that she doesn't get along with her husband but financially can't afford to actually get divorced... Most of the reasons she has for staying together seems to do with financial reasons... I'm not sure if it's considered as cheating but they act like they're divorced... I even heard her say she's only married on the paper...
