I am really sorry with what you found out. I was away on business. Only you know what is the best for you.
For me I feel free after my W left me. I don't need to put up with uncertainty and dishonesty of having an unfaithful W. Life is definately better without an unfaithful W. I have more peace. I am sure I will find a new partner again later and be happy again. I have tried my best to rescue my M. I have no regret.
Pray to God to grant you peace. Grant you strength to accept things you can't change. May peace be with you.
