I was married and lonely, now I am separated and lonely. Take it from me, it is much preferable. The thing that has changed is that at least now I have hope. Hope that someday my life will not be like this. Plus, I get the whole bed to myself and total control of the remote. I don't have to cook if I don't feel like it. There is no one around making me feel like the most undesirable and boring woman on the planet.
It was hard, but worth it. Trust me on this. Just do it.
