Only you can decide if the time is right, for you to tour alone. What a wonderful reaffirmation of confidence this will be for you, when you're ready!
Along the Pacific Coast is one of the bike tours I want to do, too, though most likely with DH. Every once in awhile, I like to repost the link to the journal of a friend of mine, Sylvia. She has been solo touring since 2007, starting with a trip down the West Coast. Enjoyable reading and some great photos to go along with the journal.

Keep planning, and the right things will come up to make it happen, when the time is right.
