Hannah that's an amazing story! Good for you! Your life needs to be conducted in accordance with your ideals and beliefs, not the opinions of society. My father never married until both his parents passed away. He lived with, and cared for them after all his siblings had moved on. I thought it was wonderful that he did that.
Both of my sons moved out of the house, one when he was 20 and the other when he was 21, so quite early. I only live with my husband.
