I am single due to my husband dying on me. How dare he! For three years after my husband died, I might as well been dead myself because that was how I felt... dead. But life goes on. Time is a good healer. I am now enjoying my new found singlehood. I am alone but I am not lonely.
I keep myself busy. I work, I volunteer, I go to the movies and theater, I joined a karaoke club even if I can't sing, I go to the library a lot, I write blogs and hubs, I visit my kids who have their own apartment, and I belong to a dating/friendship site which I haven't visited since I started hubbing... why? because I'm not really looking and I hate hurting other people's feelings.
So, do what I do, keep yourself busy. Oh I also love to read, watch tv and love donating money to the casinos. Once in a while, I also go to the racetrack and I do my own handicapping.
I never feel I'm a failure because I am on my own. Don't be... you are not a failure just because you are single.
And keep on smiling, you never know who is falling in love with your smile.
