Honestly, I like being single. I've been in two very long term relationships, and I've been living single for 10 years. I prefer being single at this point. About the only time I miss having a partner is for physical intimacy.

Sleeping alone - I have dogs, so I don't actually sleep alone. I'm not a snuggler, and I like my space, so that doesn't bother me.

Eating alone - I tend to read when I eat. If I cook, I make enough for two or three servings and freeze for later. I've also gotten good at making single serving meals. I eat healthy frozen meals or I will eat a large lunch at work and have something small for dinner. My evenings are very busy, so I'm often eating on the run anyway.

Not having someone to come home to - again, I have dogs that always greet me. But, I kind of enjoy coming home from the office and not having anyone around. It's my time to decompress from having to be around people all day. I also plan things in the evenings, so I spend time around people when I need it.

lack of affection - I'm not generally a physical person so this isn't a huge thing for me. I will cuddle with the dogs.
