I do not like living alone. I like to have people around, and at least one dog. I do, however, like being alone. I have to have a room where I can go to be alone. When my daughter visited CA for a couple of weeks last December, I enjoyed having the house to myself.
I quite like the idea of having a platonic friend to be a companion as I get older, but not actually live with me. This is assuming I have a dog, an alarm system, and cameras to keep me safe. And hearing aids if I need them. My mother took hers out at night (of course), but then she couldn't hear anything that may have alarmed her. I read too many mysteries.
I have not lived alone since I was 23 years old. First, I lived with and married my ex-husband. After that, I lived with friends for a few months, then with my current husband. When he moved to Boston, I lived with my ex-husband and a friend of ours. Then I moved to Boston and got married, had 4 kids.
I thought I'd be living alone here, except at night, but all four kids moved in. The boys ended up moving to CA, and my daughter stayed with me. Now my daughter is in CA too, and one of my sons lives with me. My son and I are moving next week to live with my cousin.
When I stayed at my mom's house for 5 months after she died, my ex-husband usually spent the night with me (he slept in the guest room). I was too nervous to sleep in a house alone; I tried it. When a fireball went through my bedroom I had no idea what it was. It was lightning, but I got really spooked thinking it was my mother. I never heard of a fireball before. Sometimes I slept at my stepdaughter's house.
My ex and I have been friends for most of my life. Always platonic, except when we were married.
