I'm not alone...I share my home with two dogs and a cat, and while they do put demands on me they don't disappoint me. I don't expect or hope for them to understand me, I like taking care of them. The dogs offer sympathy and support when I'm upset or angry without offering fixes or solutions to my emotions.
I still think it would be great to have a romantic partner, but I'm not an easy match and I love spending time alone, which means that what I gained in affection and synergy would have to be greater than what I lost in freedom and contentment.
