Burning Down The House

With all the many references in the Torah uniquely defining a man's wife as his בית (house) it then struck me as a real difficulty how the Torah is able to write

ושלחה מביתו ויצאה והיתה לאיש אחר

... how can it still be called ביתו if she's now gone??!

[Note as an aside, the connection between the latin femina/familia, and it's derivations in english feminine/family and french famme/famille]

[possible answer: see Yevamot 103b  שאני התם דאמר קרא (ויקרא יג) ושרף את הבגד אפילו בשעת שריפה קרוי בגד]
