Regulus would go back to his home, and you didn't know if he would say anything about you or try to hide you. Anything related to his life at home left you confused and apprehensive because, despite what you had told Sirius months before, now you were starting to care a lot about what would happen to you both, and you knew his parents would play a significant role in that.
