So I say forget them...two years later I notice my BB is down to 4...same monarchs, same everything else (an uneventful 2 years). Try to diploannex - bingo it works.
Since then, I've noticed the same pattern - the higher the BB the less the chance of diploannexing/vassalizing. It isn't the only factor, but it does play a role. Time, of course, is the biggest factor...
Even if you haven't raised one single soldier or set up one single TP (increase of army size or country size in provinces, respectively) the major difference is likely the two years, and luck.
When I played EU1 I might somethimes do the reload-game when trying to dip-annex, and I could fail 8-12 times before success, at exactly same situation.
Also, the longer you wait, the more likely success will become, so even two measly years could make a difference.
