Personally I wouldn't reply to the FB question. You are two separate peeps, she is moving on.

You can have your privacy, you do not have to be friendly if you don't want. And silence isn't rudeness, there is a technique called grey rock, in which you stay as boring as you can in responses. Bland, Bland, Bland such as I haven't anything going on at this point in time.

She is moving on as are you.

"WW, your apartment sounds good, no doubt you will move in swiftly and settle soon. That's good. I don't consider I am ignoring you and I will think about it."

And you think about in for half a second.
