Shelterdog, hunnybunny!
I'm single/divorced, and I have absolutely NO problem going to events or a restaurant alone. I DO have friends, and they tell me they would NEVER go to a restaurant alone. WHY!? I wonder. I actually enjoy going out to dinner alone if I'm inclined to do so. Nothing wrong with this whatsoever.
I gave up trying to meet men, and it is a very liberating feeling, once you accept it. In fact, once you do so, you may find great peace, as I have, but if you are still desirous of meeting someone, it is more likely you will do so when you are NOT looking!
