Freckles, I know and can feel exactly where you are coming from. You got used to that feeling, when you were married, of having that someone be there when you walked through the door, saying hi, giving you a hug and asking you how your day was.
When it's gone, you miss it for sure.
But instead of focusing on what was in the past, and what you miss...try to focus on everything great about how your life is now. I bet it is pretty easy to figure out some things that you like about your life these days.
