midnight kitty trouble

My roommate and i adopted a kitten about a year ago and she’s our little angel. I sleep with my door closed so our cat tends to sleep with my roommate and it’s been working for the three of us for a year but lately at around two in the morning she gets tired of my roommate and tries getting into my room. I’m not comfortable sleeping with the door open which is why she can’t sleep with me but it breaks my heart hearing her scratch and whine from outside my door because she rarely meows. wondering if anyone has suggestions so she and i can both get the sleep we want where we want ☺️
