Lexie,
I can relate to all of this! At 35, I divorced my first AH and moved into my own house. I was living alone for the first time in my life. It was a little scary and lonely at first, but wasn't long til I embraced it and loved every minute of it.
I came and went as I pleased, I could eat chips and salsa for dinner if I wanted, there was no one to consult with on home decor...it was true bliss.
Those years were such a great period of growth for me. I gained much self confidence and learned how strong I really am. I often miss it too. It's nice to share your life with someone, but being independent is so freeing!
And the best part of it all? When I cleaned the house......it stayed clean!
To anyone facing the possibility of living alone, try to approach it with an open mind, you might just find it's the best thing that's ever happened to you!
