How do you guys know when to break things off?

Im having a dilemma because I feel like my relationship is too much work for me. She expects full body massages at least once per week, and she expects great sex every day I?m with her. I often cook for myself and she cleans up around the house for the most part. She takes my dog on walks since it?s Covid and she?s at home all day, every day when I?m at work. I work 24 hour shifts as a firefighter, 56 hour work weeks, plus I work about 10 hours a week part time as an EMT. She demands that I spend all my free time with her. I have no time for friends. She seems to believe that her life is a priority over mine, generally speaking, and that my purpose in life is to make her happy. It?s Covid, so she doesn?t work or go to school. I met her when Covid started and we have been living together for about 2 months. The holidays were stressful and we argue over stupid stuff. Usually it?s because I get stressed out and she gets upset because I?m not happy 24/7, and she?s very sensitive to anything negative that comes in life. I constantly feel like I have to be her rock, and it?s weighing down on me because I?m not as mentally strong as she thinks I am. I?m slowly losing my patience and I feel like the relationship is too much work for me.
Am I trippin? I?m not sure how other men are in their relationships so I could use some perspective. She?s 32, I?m 34. She?s a retired model/Gogo dancer and has some college experience with very bad credit and no savings. She?s what men would call a 10/10 on the attractive scale, I?m also considered an attractive man. I have a college degree and a great job, but I?m a little late to the party and don?t have money saved. I spend a decent amount of money on her and catering to her lifestyle is relatively expensive. We live in a nice condo where we split the rent but she?s living off government assistance and food stamps with no inclination of getting a job when that runs out. Idk what to do because there are things I love about her. Idk if I can keep up with her demands for the rest of my life though. I have a hard time getting enough sleep because after a long day I have to stay up late having sex/massaging her/reading to her to help her sleep. Then finally when I?m sleeping she?ll go make some food in the kitchen and disturb my sleep. It?s negatively affecting my job and physical fitness because I don?t get enough rest. And she gets mad at me for wanting to work as much as I can for the future.
Please help a brother out with some possible solutions ??????
POST SCRIPT - Hello everyone. It?s me, less than 12 hours later and 1000 comments later. Wow. I?ve actually read most of the comments and DMs and they?ve all been very helpful. I appreciate every one of you for taking the time to voice your opinions and perspectives. With that said, I completely understand that there are a lot of red flags here. She contributes to the relationship in that she does support me when I need emotional support or someone to talk to. She adores me and sometimes she?ll rub my feet or my back, she?ll sometimes make food for me. And sometimes she lets me have ?me time? but only for a couple hours at a time after she?s noticed that I?m super stressed out. She does pay half of the rent, but because of her living standards, I have to pay more than I would living with roommates. But that also means I now live in a nice place, which is, well, nice.
With that said, the Covid assistance is probably running out in March, and she still makes very little effort to look for jobs. She is convinced that she is a huge asset and won?t take a job unless they pay her a lot of money. She claims to be a social media expert, since she has about 45k followers on IG, but tbh it?s probably from all the twerking she did on her page, and her fake boobs in bikinis (you know the drill). She changed her life about a year before she met me, had her boobs removed, decided to quit Gogo dancing and lived at her parents to rethink her life. Since she moved the area and met me, she has deleted all the stripper looking posts on her IG, and posted me and her all over it. She writes me sweet notes and takes lots of pictures of us, and edits videos of us out on dates and stuff. She?s very sweet in a lot of ways, abs even knows when to give me some space when I?m at work. (I work 24 hour shifts) She has goals to be a health and fitness business owner, however she has zero experience or schooling in running a company, and based on her ?cocky? ?know it all? attitude, she will have a very hard time finding business partners. It doesn?t mean she can?t be social media marketer or whatever, but she doesn?t take the time to build a solid plan, with a clear position she wants to fill.
Her getting a job is what I need to talk to her about, because if she doesn?t get one soon, I?m not sure she?ll be able to pay her share of the rent. She does have an onlyfans page (with no nudity) which gets her supplemental income every month but we all know that not a real job. Sooo yeah I need to evaluate whether or not this is worth it in the long run. It?s possible that she could land a good job eventually, but that?s pretty unlikely because she has sleeping problems and takes ambien as well as antidepressants. This means that she has a hard time being places on time. In addition to that, she has no car and I have to drive her to the grocery store and to get her meds from CVS. She doesn?t have many friends here. She does have a guy friend that she swears is strictly platonic. She?s not the type that would cheat, but I do fear that if for whatever reason I can?t keep up with her sexual appetite I could see her drifting to another guy (so far I?m doing great, like way better than anyone according to her, and I believe her lol) but yeah typing all this stuff is kind of making me scared for myself lol. I?m going to have to talk to her about a lot of things. So far I?ve alluded to a lot of these things, but I try not to make demands because I try to be the better person. Seems like ima have to start being an ******* to a certain degree to make sure she?s good for me and my health. Idk why I?m with such a dysfunctional person when I have so much to offer. I guess I value her looks immensely, at least I did. Not as much anymore obviously. I have to stop enabling her entitled behavior as many of you put it. But at the same time I can?t blame her for missing me. She just adores me and misses me, that?s why she demands I spend my free time with her. She definitely needs a job or a hobby so she can focus on herself. I just wish she had a car or at least a moped. But honesty I?m not sure how much that would help. She?s very stubborn about basically everything.
