Husband upset because I agreed with him being boring

Long post

It’ll be a year next week of marriage but been together for 8 years. My husband used to like doing stuff here and there but now for the past year in half it’s like he doesn’t. We haven’t been on a date since December, well we went to one of our nieces plays back in May so I count that as a date, So fast forward he said we will go out once a month but we haven’t that was back in January. We literally don’t do anything but sit around the house when he’s not working he’s off two days a week and works a demanding job so I don’t bother him and let him relax. The only thing I used to ask him was does he want to go on morning walks with me and our dog he always said no so I stopped asking. My family invited us to come over for the 4th of July he said no, because he wants to rest so I said okay. He then proceeded to apology and say he’s sorry he’s boring and I agreed with him that he’s acting boring but told him I understand that he be tired but it’ll be nice to do stuff together here and there even if it’s just playing video games together. I also asked him and told him that I would never force him to do anything he doesn’t want to do because that’s selfish so if he doesn’t want to do anything then that’s okay. That conversation happened yesterday now today he’s texting me saying he’s going to go to the family event and he knows he’s boring as hell etc.

I can tell that conversation bothered him but why do I feel bad? Is it because I’m in the wrong? He works so much and I literally want him to get rest as much as possible but am I wrong for wanting to get out the house and do stuff with him? He’s the bread winner since I was let go from my job because I’m a full time medical student and my husband told me to focus on school. All I want is one date once a month will be great, even if it’s to Waffle House, I don’t want us to be that boring couple who doesn’t do anything. We don’t have children yet. So I’m not understanding why he got mad at me when I agreed with him about him being boring. He used not to be we went on dates all the time even if it was to walk around a book store.
