In my book, "Your Writing Coach," I have a chapter on how to get emotional support for your writing. In a podcast interview in the Guardian, Sue Townsend, author of the Adrian Mole books, talks about this:
"She explains that much of Adrian's character is based on her own experience as a "secret" writer for years, put off from going public with her work by a disapproving first husband. Her second husband proved much more encouraging, and after a creative writing playwriting course at a Leicester theatre, Adrian was born after an actor asked for an audition piece."
The lesson: if your husband/wife/partner doesn't support your writing, get a new one...or at least find a writing group or course (online if you can't find one locally). You deserve to be supported in doing whatever is meaningful to you--don't give it up!
