Should I Leave My Boyfriend?

My boyfriend (29 M) and I (28 F) have been together for 7 years. Our relationship started out good as any other, we were inseparable, in love and at that time, I could easily picture a future with him. He checked off every box on my checklist at the time and I wanted to be with him 24/7. By our three year mark, we both had moved in together and were living the post grad life. I was able to get a good paying job right out of college and worked as a waitress a little bit on the side too. He however, was struggling. He was jobless and decided that he wanted to go back to school. I was in full support of his decision to continue his education but it became a little rough for me. I found myself being the sole provider for the both of us and I didn't mind it at all. I knew that the graduate program that he was in required a lot of time and commitment and working a part-time job while in this program was not feasible for him. So I made sure he had nothing to focus on but his studies. I worked my full time job and served an additional 30 hours every weekend too to make sure that he never missed a meal and he received everything that he wanted.

Fast forward four years later to now, I'm two months into the unemployed life and have really nothing going on for myself. My mental state sucks, I am struggling to get out of this rut that I am in and I don't know what to do with my life anymore. I've applied to numerous jobs, with no luck and my boyfriend makes sure to remind me daily that it isn't fair for him to be the only one paying for rent, utilities, internet etc. I get it, we agreed to split things equally but did he really forget about the past four years? He currently has a list of bills that he's paid for by himself so far and is keeping track of it all so that when I get a job, I can pay him back. I think his list is a bit ridiculous and it makes me so angry thinking about it. I spent the past four years working 70+ hours weekly to make sure we both were staying afloat. Now that I'm no longer working, and he's the only one working, it's a problem? I've started to resent him and can't stand to be around him anymore. I thought that he would be understanding of my situation because I've helped him so much but I guess not. I've tried and pleaded with him to just give me time to get myself back together but those attempts have turned into him threatening to "evict" me out of our apartment for not being able to pay my part. Is this my cue to leave? I'm so hurt and pissed.

EDIT: I am so blown away by the overwhelming support and all of your kind words and messages. I'm getting teary eyed reading all of your comments and am truly thankful that an online community can show more love and support to a stranger like me, than my boyfriend of 7 years. Thank you all and I appreciate you all so much. <3 -To answer some questions, we're not married. I am unemployed because I was laid off. I have spoken to him about how I feel and I've brought up the past 4 years to him many times. He doesn't seem to care and his response to me bringing up what I've done for him is always something along the lines of, "I never asked you to, you willingly did that yourself." Additionally, in my above post, I said graduate school to keep it vague but to be more specific, he was in dental school. Not that that justifies anything but I agree with you all, he is selfish and entitled. I am working on my own list now, going back on bank statements and what not for the past 4 years, calculating everything, making sure not to miss a thing. Next time he wants to be petty and pull out his list, I’ll have mine ready as well. Our current lease is ending in June 2024 and we both agreed to not renew because he wants to buy a home. I’ve made it clear to him that after our lease, I want no remaining ties with him. I told him that if I can’t get back my time and money that I’ve invested in him, he shouldn’t expect anything from me either for the remainder of our lease and so on. He’s agreed to look for a home on his own and I’m going to use the remainder of the lease to take care of myself, find a new job and save up as much as I can so that I can get as far away from him and close this chapter of my life.
I’m so disappointed that I wasted my 20s taking care of an ungrateful POS but I guess it is what it is. Never will I make a man a priority over myself ever again.
