Carr, Robyn. Virgin River series.

"Four years ago, Air Force sweethearts Franci Duncan and Sean Riordan reached an impasse. She wanted marriage and a family. He didn't. But a chance meeting proves that the bitter breakup hasn't cooled their sizzling chemistry. Sean has settled down in spite of himself--he's not the cocky young fighter pilot he was when Franci left, and he wants them to try again. After all, they have a history, but that's not all they share. Franci's secret reason for walking away when Sean refused to commit is now three and a half: a red-headed cherub named Rosie who shares her daddy's emerald green eyes."--p. [4] of cover
