I Get Stressed out Whenever My Son and His Family Visit; It Might Be Time to Make Some Space

I’m a woman in my 50s working part-time. I live with my pensioner husband, who is in his 60s. My son, who is in his 30s and lives in a neighboring prefecture, is married and has a little child. He and his family visit us several times a year, and when they do, they clearly take for granted that they are guests, which really stresses me out.
