Why do women cheat instead of breaking up?

A lot of reasons, probably similar to the ones that men cheat too. :) Someone close to me cheated on their man that they were technically married to because they felt like they couldn't survive independently (finance-wise), they 'had to' cheat in order to retain a part of their sanity and because the stakes were too high if the other relationship didn't work out and breaking up would mean that there would have been no fallback.

They cheat for someone sort of shield to help the pain they are emotionally going through..they dont want to loose thier significant other but st the same time if that someone us not giving them what they need to go looking for it in another individual

They don’t wanna feel alone even if the relationship is not happy and they wish for something else they don’t feel worthy or good enough to risk the relationship

Unfortunately, this is entirely situational. Did this happen to you recently? or do you have experience with this? Are you concerned that you will be cheated on?

This question isn't limited to just women. People are selfish. it is good to have the cake and eat it.

Probably for a variety of reasons. In my experience, one reason is because they're dissatisfied with the relationship and they aren't getting what they need from their partner even though they love them. And they're afraid to have that difficult conversation to end things and hurt someone they love, and maybe some part of them is afraid to lose that partner as well. And cheating perhaps seems like an easier way to do that and be the "bad guy" so you don't have to have those tough conversations.

It is hard to pinpoint why women cheat. Sometimes, a person think they can find more passion, companionship, and fun from someone else. They love the person they are with or do not want to give up what they have, i.e., money, status, associations, family. Affairs can be like taking a holiday. I would say most people do not want to give up their main relationship but feel they are missing something. Because of this, they try to find it in another person.

Is not only women that could cheat, men do it too unfortunately. And the main reason someone cheats and don't break up is because they want to have a backup plan

Usually they cheat because they might not want to end the relationship. They might not want to hurt the man feelings, so they cheat to avoid breakups.

Some Women cheat most of the times expecting their own interests and so mean try to cheat instead of Break up. The person on the other side gets hurt badly not knowing the things properly and in the end lead himself into Depression. Some Women expect some gain and when this gain is not achieved they cheat instead of Break up.
