You said it yourself. When you were getting closer to advancing to the next league, you faced harder and harder opponents.

That's the idea of the matchmaking. Keep everyone at a 50 percent win rate. If the MM sees you trashing Golds, they'll pit you against Experts. If they see you getting trashed by Experts, they'll pit you against Golds. That's probably one of the reasons you were facing Experts and Diamonds as a Gold. They were either higher-up players that were losing constantly, or you were a lower-down player that was winning.
