Take The Key Away From Your Mama To Our House! Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - "Take The Key Away From Mama?' Guys, living with my man now for the last 8 months. Moved into his house. All is great except 1 thing. HIS MAMA HAS A KEY TO OUR HOUSE and she shows up whenever she wants and when we are not there. She'll clean up, do his laundry and stuff. BUT what bothers me the most is she'll show up anytime. Is it time for me to tell my man TO TAKE THE KEY AWAY FROM HIS MAMA!!!???
