Woman bonks man (wheee!)
Women loses man (dang!)
Woman has baby (oops)
Woman never gets around to telling man (wot, I wuz busy!)
Man re-appears (oops?)
Woman marries man (yay?)
Can someone please explain how, in a contemporary setting, it is really possibly to misplace the babydaddy for a decade or so? The heroine doesn't care about fathers' rights? Doesn't know how to Google? Wow, nice gal.
The resulting books generally seemed to be devoid of any real conflict as by the time the parents are reunited (in these post-Scarlet-Letter times) there really isn't anything substantive keeping them apart. This causes the author to have to reel out a series of misunderstandings, minor furors (storms, sick pets/children, burst plumbing etc) and general scenery chewing to get a book's worth of plot bends (not really 'twists' per se) out of the story.
The only upside of the melodrama is that by the end of it I am convinced the hero and heroine 'deserve' each other--although the kid may be better off in foster care. Whatever button this trope is meant to be pushing, apparently I don't have it. Maybe one of y'all can explain it to me....
