Holly Durst may have voted off
Blake Julian on Bachelor Pad this week
, but the note she handed him at the rose ceremony – saying that it wasn't the end for them – has turned out to be rather telling.
That's because the pair, both 28, who have flirted all season long, are now engaged to be married, a source tells PEOPLE.
Their courtship was always complicated, given that Durst's former fiancé Michael Stagliano was also competing on the show, and still had feelings for her. And Julian himself was involved with fellow contestant
Melissa Schreiber throughout much of the season.
But freed from the Bachelor Pad
mansion, it appears their flirting has blossomed into true love.
The season 2 finale of Bachelor Pad
airs Monday (8 p.m. ET) on ABC.
