Making dinner is exhausting!

Ok guys, first I want to start by saying that my husband really isn't a bad person. Most of the time he's really amazing and supportive of me. I don't believe in down talking him in front of people I know, but I feel like I need to vent. So, I'll do it here.

We've been ttc and are having a little difficulty. I started a very strict diet to try to shed some weight hoping that it will making ttc easier. However, because of it, I end up having to cook two meals: one for me and one for him. Cooking in itself is exhausting for me (I'm not the best but I try). Tonight I asked him what he wanted for dinner. He said it didn't matter so I offered to order out: it's Saturday, we've both been busy all day, and I can get something legal for me and for him without much effort because, quite honestly, I'm tired.

He said that he didn't want to order out but preferred something from the freezer. It was 8 pm. That meant I had to cook. I relunctly went and started cooking and he came in and said that he wasn't trying to be a jerk but was just thinking of cost. Ok, fine. I get that. I told him my biggest problem was that he just wasn't up front with me from the beginning. Like, if you wanted that, why didn't you just say so when I asked? I then explained how exhausting running a house is (cooking, cleaning, do dishes, clothes, etc.) and that if he'd just tell me what he wants for dinner, it would make my life easier. The response I got was that he lived on his own for almost ten years and did all of that after working seven days a week and it wasn't that hard. He didn't think it should be that hard for me. In the end, he agreed to let me know what he wants for dinner from now on, but I can't stop thinking of that comment. Like, am I being petty? I'm a school teacher and work 5 days a week with homework on most days. I just felt like he didn't have a clue or appreciate what I do for our home. What are your thoughts?
