Hi Jeanne! Well, it sounds to me like you have 3 options here. 1) reread and dive back into that contemporary woman’s story; 2) pick the historical back up and decide what type of story it is if it isn’t a romance (I’m guessing that’s what you thought it was going to be when you began?) and continue on with it; or 3) start something entirely new!
If you start rereading those two tales that are partly written and just can’t get interested in them enough, then I’d say see if there is a clutch of characters reading outdated magazines in your muse’s waiting room and find out what sort of tale they’d like you to hire them to play out. Anything like that hanging about?
