Is OTHER wrong in the post ? POST : Background information, I'm gay. My boyfriend and I have been dating for about three months, though we dated briefly about three years ago before work took us to different states. We got together once we were living in the same city. We're both in our 20's, he is two years older than I am and makes more money -- but not exponentially more. This is important later.

With the holidays, I've been staying over at his house a lot. He has a dog and a home, where I have an apartment and a roommate. They're both nice places, but it sort of makes sense to be at his place rather than mine. We order food via Door Dash / Uber Eats fairly frequently, I bring food home on my way from work, or we eat groceries that he purchased.

This is the important point. About two weeks ago he got upset while we were out to dinner with some friends, put a $20 on the table, and left. I sent him a text that night but he didn't respond. I figured he needed a little space so I stayed at my place. After a few days of not getting any texts, I went to his house to talk. He told me that while the friend thing upset him, what he was really upset about was the fact that I hadn't offered to pay for his meal. He felt like he was paying for a disproportionate amount of things with me staying at his house, eating his food, etc.

I was taken aback. I've never been called stingy by anyone in my life. In fact, and I don't mean this to brag, I'm known as being really generous. We grew up fairly poor and I have been quite lucky in life -- I go out of my way to pay for meals for my employees, pay for family outings, etc. It's just a part of who I am. Additionally, it felt really weird to be arguing about a couple hundred dollars when he spends money on expensive clothing, decor, etc. on a daily basis. We're talking thousands of dollars on a whim because he doesn't like the color of something.

Long story short, I apologized if things had gotten out of whack financially. I certainly didn't feel like they had given the back of the napkin math I was doing, and I told him as much, but I said I figured it was possible since I don't really keep an accounting ledger in my head. We came to an arrangement that he would continue paying for groceries, etc. and I would pay for meals / drinks anytime we go out. Fine, right?  
Nope. On Tuesday this week, he told me that he needed to do a lot of work at home and that I should sleep at my own place. Cool. I didn't really hear from him for 3 days. I sent a couple of texts, which he responded to with one-liners but nothing else. Then after work last night, I went over to his place sans-invite and he told me that work has been stressful, but more importantly he continues to feel like "he is taking care of me" by me being at his place. I told him the only reason I stayed over was that I wanted to spend time with him. The argument didn't really go anywhere. He told me that's the way he feels and I told him that I think he is wrong.

He then wanted to have a night in and have me to stay over, but I was upset by the argument and I left. I dunno, Reddit. I try to be a super reasonable person but how the hell am I supposed to feel comfortable around someone if I know they're keeping a running tab for every bottle of water, cup of coffee, or frozen pizza I consume? I have absolutely 0 desire to be at his house anymore with this now becoming a recurring issue for him, but he can't really come and stay at my place without making arrangements for the dog. Am I the asshole for not wanting to stay at my boyfriend's place anymore?
