Luke; No, this is not right. It should feel wrong to you. Where are you at in all of this? Are you done? If you are I would tell your W this is unacceptable, and then tell her what you want.
On the other hand, if you are not done, I would tell her this would be unacceptable, and then tell her what you want and why.
Sorry, not much different I know, but after 3 years, and 12 mos w/ OM, I think you have to dicide first what you want for you, then see what it would take to get there.
Is it time for beyond the last resort? I would think after all this time something pretty drastic is going to be required to shake up the dynamic. Maybe?
