I have been divorced for 4 years now. I too, was never "alone" until Oct. 30, 2004 when he left. 

I stayed in the marriage for way too long b/c of that fear of being alone.  It took a very long time for me to adjust and the thing is, I still haven't done it completely and now realize that it is not possible to do so, at least not for me, who is also a big people person.  I am still single and I admit, I often hope for the day when I can find someone to share my days with. 

I love your blog. I relate so much to your experiences and I want to thank you for putting into words what it is I often feel.
