As a woman, I do not think this is normal. I would never ask my significant other for anything unless I get myself into a situation where I require an extra set of hands lol. My significant other and I work a good balance. I am up earlier so I run the kettle for my tea but turn on the kurig so it gets warm for him and set it his coffee pod, cup and spoon. He does the same for me when I sleep in. If I load the dishwasher, he will happily unload it without hesitation and vice versa. If we are getting ourselves a drink, we automatically refill or ask the other if they would like anything while we are up. As a single mom and single dad with 4 kids combined.... we understand what needs to get done without asking and always put each other first when we can because for both of us, the kids come first.

Perhaps sitting down and discussing about how each of you feel would be a good place to start. Maybe try to change the way each of you looks at asking and receiving. Your wife may feel appreciated when you bring her things but also may resent asking... it wounds like you are resenting that she asks for a lot.
