When the person you loved betrays you, it is a big tragedy
And I'm so sorry this happened to you.

I understand that you do not want to live without a family. But it seems to me that living with a person you don't want to live with for the rest of your life is also a bad idea.

Maybe it's better to leave your wife now. Because you will no longer have love and trust. But if you go, you will still have a chance to find a person who will love you and who will be faithful to you. All people deserve to be with people who value them.
