You need to understand that betrayal is a gross manifestation of disrespect for you. What do you do when you are treated extremely badly in any other situation? Do you stay or try to never communicate with a person who shows disrespect again? I think the answer is clear enough.

Here the problem is different. Many women worry about what will happen next if they make such a decision. There is a sense of uncertainty. That you won't be able to find someone better anymore. Or perhaps the problem is banal in financial matters. But, in my opinion, it is not necessary to worry about what will happen after the completion of such a relationship. And for the fact that you stay in them. After all, you will never experience happiness in this relationship anyway.
