Congratulations on finishing a novel! And good luck once you send your baby out into the wide world.
If you decide to try to self-publish, keep in mind the words of John Scalzi: "The money should flow to you."
PS: And ignore anyone who sneers at you for trying a 'girly romance novel'. Tom Huff tried to make a living selling he-man action stories, and was finally encouraged to try selling a romance novel under a pen name.
That name? Jennifer Wilde. That book? Love's Tender Fury, a book people of a Certain Age will remember.
