If the W opens up and wants to talk about her issues to Dev, he can listen and validate. But the point here is that Dev is not a gay boyfriend available all the time to listen to her "problems" while she carries on an active affair. Don't want to make a habit out of this like Oxford. Oh lord! No!!!
Yes, Dev will need to work hard to limit communications to kids etc. but not entirely close off W if she brings up R talk. No talks like Oxford and his W. Perish that thought!
