Hi TIF,
It is good that the two of you can get on in the pressure-cooker atmosphere of being cooped up together so much. It is putting a strain on a lot of relationships.
Even if the direction of change is overall positive, the situation is obviously not ideal and I'm still looking for improvements.
Given the fact that the key sticking points are the same today as they were three months ago - same job, not looking for another, regular contact with her AP - are there any actions that you could take to influence/encourage/motivate your wife to start making the improvements that you would like to see.
Actually, 'improvements' is probably a misnomer for them; 'fundamental requirements' is what they really are.
I am not trying to give you a hard time, but it seems like observation and analysis alone are unlikely to make your wife feel any sense of urgency to make the changes that you need her to make.
And part of that might stem from you giving her the impression that you have no sense of urgency about the changes being made.
Please understand, that is not a criticism of you, or in any way blaming you. I want this to work out for you, and what I am trying to say is that if you remain standing back, watching, and making notes, without letting her know that the current status quo has to change, you may be working against your own best interests.
As things stand, there are no deadlines, no targets, no plan, no strategy (short, medium, or long-term)...
Is there anything at all that would make your wife think that exactly the same situation cannot carry on unchanged for the next decade? If there is not, might that explain why she has made no changes?
Is it possible that your wife feels secure that although you occasionally say sharp words when she tests the water by suggesting she 'almost' wants to normalize her relationship with a man she actively pursued (delete the word 'almost' and the statement becomes more honest), you basically accept the way things are? And that a few barbed comments are a small price to pay for prolonging a situation she seems perfectly comfortable in?
This is not to say that you suddenly have to become a Navy Seal and apply 'shock and awe'. Nor is it a suggestion that you force her to do anything. Rather, it a suggestion that you become more proactive in stating what you need to be changed if you are going to remain in the marriage. What your boundaries are. What is, and is not acceptable to you.
Now, that is not forcing her to do anything other than make a decision about what her priorities are. She can go any way that she wants, but the point is, so can you.
As things stand, she does not have to make any decisions or any changes, so she is not making any. And until that dynamic changes, she is not going to make any changes to her job or her contact with her affair partner.
A good starting point would be to ask her, "How much longer is this going to go on?", to kick off a discussion that makes it clear to her that the current status quo is living on borrowed time. And to make her own the reality that she is deliberately prolonging the situation for a reason, fully aware that it makes you uncomfortable and insecure.
It is time to start calling her out, or she is never going to make the changes that you need her to make.
