Sam2,
The OP said it would take 15 minutes for her husband to get to the office. Because she knows he won’t come for that length of time, Ba’alah Ba’ir might not help according to Reb Moshe (other poskim hold that it still helps but I can’t remember whom).
(I say “might” because I think Reb Moshe was dealing with a case where it would be hours before the Husband could return.)
