Answer it like it's from a business associate, trying to work out the logistics of some business meetings with you. You'd be civil (even friendly), helpful, informative, right?
Ignore any of the personal stuff, and just answer the logistics stuff. Be courteous and responsive.
You'd be best to just assume thru all of this, Johnnie, that yeah, she IS spending time with OM. It helps to assume the worst, and then just plan accordingly.
