Well, I was never looking for love in my youth, unlike many in their late teens and early 20's. Love just found me.
So I would not have an issue being alone but I would not trade the last 43 years of my love life for anything.
My mom was a widow for 46 years and made it clear she had no interest in dating or being married again. I think my parents had a great marriage, but my dad was terminally ill for 2 years, she cared for him, she was working full time, and raising me, and she was just ready to do what she wanted to, when she wanted to after I was out of the house. And she deserved that. Besides, she said every man her age was looking for a cook, maid or nurse and she wasn't about doing that.
