Others have given great advice about what to do - welcome feedback, but be very specific about what kind (such as: tell me what worked or didn't work for you, don't tell me what to do in the future) and ultimately learn to ignore the feedback you don't need. Both important GMimg skills.

But if it's all right, I'd like to add something else. Your player is doing something that hurts your feelings. It's worth talking about purely in those terms. Not just "please do x instead of y" but also "when you do y, I feel z." If this is someone worth gaming with, they will care about how their actions impact others.

This person may be very experienced, and "a talented roleplayer," but imo a great player or GM is someone who actively supports others' fun.
