What your boyfriend had asked of you was simple. Taking what you need and going to your parents' house for two days.

In the morning, his rut started and he had took his suppressants. He knows that the effect won't last long, so he gave you half an hour to leave. After that time he would return home and spend the two days alone. He knew that if you are present during his rut, he would not be able to contain or control himself. You are still in the house and you have 5 minutes left to leave.
