You are not writing about the context, so I can only guess.

I suppose that a person who is successful and has also experienced betrayal from a spouse/partner did not take care of balance in life. Each of our lives can be divided into areas such as family/friends, money/career, health, personal development, time for oneself/hobbies. A successful person, in my opinion, is someone who succeeds in all of these areas. Focusing only on one - for example, on a career, can easily lead to losing contact with family, spouse, children, friends, and sometimes even with oneself.

It is a simple recipe for problems such as betrayal. Unfortunately, a person who commits betrayal often seeks what they do not get from their partner. And that is the first thing one must realize. Have you ever betrayed first by putting the achievement of success on a pedestal? If you choose to be in a relationship, you should take care of it, money will not solve everything. The second issue is verifying your values. And the third is talking and changing behavior.

Of course, you can decide to break up, acknowledging that you do not want to "be" in such a relationship anymore.

You can perceive betrayal in different ways and react accordingly. You must accept that it happened and think about what to do next.

Вот как справиться с изменой как успешному человеку?
