This sentence is incomplete: it doesn't make much sense on its own and it's difficult to guess exactly what it means. However, if I had to guess, the second half of the sentence could mean: "first, by acknowledging that you had divulged [something]..." where "divulged" means "made something known" or "made something public" or "brought something out into the open". The phrase "your divulging" can be expressed differently as "that you had divulged". For example: "He complained that you had divulged his secret" = "He complained about your divulging his secret" = "He complained about your having divulged his secret". Using "your divulging" or "your having divulged" in these contexts is grammatically correct (and I would say these things); however, it is much more common to hear people say "He complained about you divulging/ about you having divulged his secret", which many people think is clearer.
