Should I tell him I'm unhappy??

DISCLAIMER: Before anyone comments anything nasty... Please realize I'm aware I've made some mistakes. I'm looking for genuine advice, not to be bashed on.

My boyfriend and I have been together for over 6 years now. I'm 23 and he's 24. We've been together since senior year of high school and did long distance until I moved back from college and in with him in March 2020. I am getting increasingly unhappy... for many reasons. I understand that living with someone isn't always easy, but he makes it miserable. He's very clean, which I appreciate. But he does not help with anything around the house unless I ask him. Like a trash can could be overflowing and he'll continue to throw trash in it. We could need the toilet paper restocked in our bathroom and he just ignores it then bitches at me when he runs out, even if he took the last roll off the shelf. He bitches and makes excuses when I ask him to do anything, and I have to specify that I want it done NOW because if I don't, he drags his feet until I do it myself. I cook, I do all the laundry, I vacuum and wash the floors every Sunday, I clean the bathrooms, I clean the kitchen and I take care of our dog. He changes our bedsheets once a week.

Secondly, he will not propose. We both made it clear we want to get married since the beginning of our relationship. Now he uses every excuse in the book and get angry with anyone who brings it up, including me. We both have very good, stable jobs. He's a firefighter, and he keeps making excuses that he's waiting for things to propose. To get on a good full time department, which he is. To get off probation, which he is. To get on his dream department, which he is now in the process of. To graduate their academy. It's always another damn excuse and something more I have to wait for.

We own a house together because when the interest rates dropped, he said he was buying with or without me. I could live with him, but wouldn't be allowed to put my name on the house even after we got married and even if I paid half the mortgage, all because I didn't put anything down. So I caved and bought the house because I wanted financial stake in it too. Yes, that was a fucking mistake.

He got me a dog for my birthday because I've wanted my own dog forever and now we have a house, therefore the room for one. Yes, another mistake, although not one I regret because my dog is like my child and is spoiled to no end. I had the impression that she was going to be OUR dog, but he insists that she's mine only when it's convenient for him. Like when it's time for vet bills, taking her outside or cleaning up after her.

I'm so unhappy... and I'm stuck. I love him very much and it's not like he abuses me, but I feel so disrespected, unappreciated and taken advantage of. Should I tell him...? I don't want to start a massive fight. I'm just tired of being miserable and feeling like shit about myself.
