In case you don’t normally read comments, my First has contributed some thoughtful perspectives in the comments of these posts about him (he posts as Her First):
I had a blog around the time that we were in a relationship, possibly some journals also. I was curious enough about how I felt at the time to go looking for them.
I found the blog content and some old emails. My blog writing is cold, factual, brutally honest, especially given I know my First read it (he wrote in it at least once). Quite hard to read.
I haven’t located any journals yet.
So, probably more to come about him.
