I’m resenting my boyfriend for ignoring my desire to get rid of our dog

My boyfriend and I had decided to get a dog and two weeks ago found one we thought was perfect. But it turns out it’s way way too much work for me. I’m disabled and unable to walk it, and it’s one of those dogs that ruins your house and is aggressive if you don’t walk it at least 2-4 miles a day. I told him I realized I’m actually a cat person and not a dog person at all, and want to get rid of it. He’s fallen in love with it tho but I’ve come to resent both him and the dog. It’s ruined all my favorite belongings and is an energy drain. I have enough to deal with already. His mother is taking it during the day until it learns to stop biting, but that means i will eventually be expected to take care of it all day while he’s at work, and I had told him you can keep the dog if you find someone else to care for it during the day. But he won’t do that. I have my own health to think of and I have things I actually want to be doing with my time. I told him I feel trapped but he doesn’t listen. He thinks how I feel about the dog will change but I’ve told him over and over it really won’t. Im resenting not being heard or listened to and that he’s not taking into account how I feel or what I actually need. This is similar to a past relationship I just freed myself of, but less extreme. Im thinking I need to leave. Does anyone have any advice? I would really appreciate it.
