Rebshidduch, there is a concept called בעלה בעיר “her husband is in the city”. According to halacha, if a woman’s husband is in the same city, the laws of yichud are more lenient. This is because there is a fear that he may come home at any moment.
One should ask a sheilah before applying this leniency as it may depend on the situation.
It definitely can make things easier in certain circumstances:
1. When you have a Frum workman over
2. If you have a boy boarding/living by you.
I know someone who relied on this leniency when a teenage boy who couldn’t live at home was living by them. Otherwise, he would never have been able to be in the house when she was home and her husband wasn’t which would make things very complicated, since women are generally home a lot more than their husbands.
