I feel used. iin

My boyfriend and I live separately. I cook for him all the time, because we spend most of the time at my place. Last weekend he came to my place on Saturday before dinner. I made dinner for him, and breakfast and lunch the following day. I put dinner to bake in the oven a bit later than usual, and because he often leaves by then, I didn't think he would stick around... Because dinner was taking longer than expected, and he was ready to go home, he became grumpy. And kept asking when dinner would be ready, and making smarty pants comments about why dinner wasn't ready yet. He waited until dinner was ready, but was clearly unhappy and didn't talk much. As soon as we ate, he left.

He has now done this a few times, where if I hadn't started dinner on a Sunday by a certain time, he would ask what time I'd be making dinner, and then as soon as he'd eat, he would leave.

I can't help but feel used. Is it normal that I feel this way?
