My wife and I moved in with my parents for 5 months a few years back. Our lease expired and construction on our home wasnt complete yet. Was great. Mom cooked and cleaned. Did my laundry. Dad did the yard work and we went golfing and got drunk every Sunday. He loved walking and playing with our dog. Who happened to gain about 15 lbs when we lived there. They enjoyed toast and bacon for breakfast together.
Plus their house is pretty big and they have a 1st floor master. So my wife and I had the entire upstairs to ourselves and was like we lived there alone almost. Was great. But 5 months was enough.
I would have kicked your butts out before 5 months. Sounds like you took advantage of the situation and didn't contribute any help.
