1. That you are lonely. 2. That it is not by choice.
I love living alone but my boyfriend is here a lot and I'm over there a lot. Even without a boyfriend, I love living alone. I don't think I'll ever marry again.
That living alone is unhealthy. Which is not true. I like being alone. The last 5 years of my previous marriage, I lived alone. My son was at college and ex lived in another town during the week and I loved it (he had a great dislike for me anyway). When I moved in with my current husband, he was just as quiet as I and we moved through this home like ninjas.
He does his thing, I do mine. We spend the weekends together and it's great. Still, very quiet and not many words spoken, just a lot of hand-holding.
