You have had a rough fifteen years since the loss of your husband, I'm sorry to hear that. Taking care of aging parents isn't an easy feat, and I respect you for having been there 24/7 to help them. It says a lot about your character!
I too currently prefer to be alone, and I don't need a relationship to fulfill me. I do understand the occasional loneliness that you experience. I do too.
Great color selections, fun prints and black is a great color that goes with everything!
