This would be perfectly okay IF their R is in a good place.
Don't ask (TELL) her to do anything. Be a big boy and call XXX yourself. Don't tell W that you did this. STFU is the rule. You are no longer a team.
As far as "I have something more important"...whatever it is...watching paint dry... SHE DOESN'T WANT TO WORK ON THE MARRIAGE.....you are agreeing with her. You hear her..you are supporting her decision. Again, this is not what you say to someone when the R is in a good place.
