If I were in that situation, I’d likely feel hurt, confused, and undervalued. After nine years, being reduced to just “a girlfriend” would feel dismissive of the time, effort, and emotional investment put into the relationship. It would raise a lot of questions about the other person’s commitment, priorities, and the true nature of the connection after such a long period together. It would also likely make me reassess what I truly want in the relationship and whether it aligns with my needs and expectations.
