What Rose said, plus one or two other thoughts.

You keep looking for the evidence she wants it over, locking you out, sleeping with another man and not wanting marriage counseling?

There is a platitudes reminds me of.

There was a great flood, a man of faith was left stranded month roof of his house with no way off.He was utterly convinced his God would save him.

After a couple of hours a guy in a small boat passed he stopped and asked this man of faith if he wanted a ride off the roof to land.

The man on the roof said "no...my God will provide, he will save me."
The man in the boat shrugged and went on his way.

The day wore on and a rescue boat came by, they stopped asking the man on the roof to come with them.
His reply was the same.." God will provide"

As night fell the weather worsened, the hunkered down for the night.
Later a helicopter passing over head, circling they lowered down a rescue line but the an once again refused.

"I will be fine.y God will save me he will provide."

The storm worsened the waters rose and the man of faith prayed calling out to God, "why have you forsaken me?"
Eventually he drowned.

In heaven the man was bemused and bewildered and,a little annoyed.

"God, I have been a good man all my life. I prayed regularly, worked for the betterment of others, have my time to those in need, why did you not hear my prayers. Why did you let me perish."

God replies.."I sent you two boats and a helicopter...what more did you require?"

This man refused to see the obvious because it didn't suit his view of whAt an intervention from God would look like.

In a similar way I see you missing the obvious with your wife because it doesn't suit you to accept it.

She isn't filing for divorce because for it doesn't suit her motives. Whatever they might be, probably financial. You might turn yourself inside out trying to figure it out. Irony change the situation.

I do wish you all the best Dadfm. Please take all the re you need but stay focused on the reality of it.
