A question I have is is it unfair or wrong of me to demand he cut ties with this woman? The fact that he didn't do it already says a lot.. His excuse is that she is a part of a group of friends, but is that just another excuse? He completely betrayed my trust with her and I feel like putting myself in a position where my husband continues to maintain a friendship with her is just doing myself a disservice. How do I navigate this issue and stand up for myself moving forward? The way I feel is I do not want to continue on with a life with him if we cannot agree on this. Am I being unreasonable?
Not unfair or wrong in any sort to say that. You two are married.
How do you stand up and continue moving forward? By just taking care of yourself. One day at a time. One hour at a time. And coming here. And talking to friends, ICs, whatever it takes. You will be fine!
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
