Among the redpill community, there is the belief that if a female fucks up in a big way then you should dump her and go complete no contact. There is a much better way to handle this situation.

Say for instance, you are allow a female to work her way up to a ltr and after a few weeks, she fucks some other guy. Oops. What would your normal action be? In most cases the answer would be to cut her off and disappear forever. Although this action is great for self-loving masturbation, it's costing you pussy and stopping you from reaching a higher level: no contact is reserved for personalities that you can't tolerate -females that get on your nerves to the point where you no longer want to fuck them.

First off, lose the ego and look at the situation objectively. This chick obviously isn't ltr material, but maybe she has some other value. Can she cook, suck a mean dick, has money, has connections, gives good massages, etc? You will need to put your emotions and butthurt aside and use her. Use her like you would use a toothbrush in the morning - do it absentmindedly.

After she cheats or disrespects you, instead of walking away forever try one last thing. Go cold on her, turn off your emotions and soft next her. Soft next her as if you're going ghost. Don't speak to her until she's apologetic, sweet, and feminine again. Only then should you accept her back as an almost plate - fwb. Once you accept her back, keep your emotional distance. As long as she is sweet and feminine, allow her to: be around you, speak to you, and do things for you. It's very important that you get her to do things for you. The only place in your life that she is ever allowed to have is as your do-girl. She's now an orbiter. Once she slips back into her old ways and stops doing what you like, soft next her again until she comes back as sweet, feminine, and humble. Demand her best with your actions. Do not accept anything less.
