I Don't Know What To Do? Help! Please! :(

Hello Everyone! I am new to this forum. I've read so many stories similar to my relationship. I am not married to my significant other but we act like we are. I am in a loving relationship with my boyfriend for almost three years. When we first started dating, he had everything under control (A Job, Rental House, Car, Goals, Motivation) But when COVID-19 hit, it really messed him up. He lost his job which he hated any way. He went back to school to finish his last class to graduate with his bachelors' but unfortunately, he flunked out of his class due not putting enough time and effort into studying because he would get so easily distracted. He would never go to class, I had to motivate him to go but that did not work. He would get so wrapped up with the house chores, he would not try to study or he would finish his homework 2 hours before its due. He dropped out school again. I tried encouraging and supporting him to go back but he's depressed. For the past 2 years, he's been staying in the house and worrying about petty things (chores, fixing up the house). I've been working non stop full time (12 hour shifts) and Its tiring because I get home sometimes I would have to cook and clean. He would be in bed all day or he would be stuck in the couch. He does not know how to take care of himself, no showers, brushing teeth, or eating. Lately I feel like I am turning into a parent. I would call him and ask if he ate, looked for a job, showered? No he didn't do any of those things, he's stuck playing videogames till 4am.  I begged him for a year to seek professional help, find a job,and etc. I had to threaten to leave him so he knows I am serious. I am not happy with him anymore. I feel like I am puling all the weight. I love him but I have to care for myself more. We got into a huge fight and I am staying at a hotel to cool off. I am studying ADHD to understand him more but its hard! He's admitted into getting help but its ROUGH! He just started therapy but its also a struggle. He'll Gaslight and Manipulate me when we argue, makes it seem like its my fault. I am barley home. I leave the house at 7:30am and come home at 8:00pm. I snapped and I am sick and tired of pulling the weight. He's very entilited and able getting money from his parents. He literally bought a house because they gave him a loan for 50K. He just daytrades to make money but since were about to head into WWIII the stocks are sinking. I wanted to save up OUR money to buy a house which is rightfully ours, money we worked hard for. I am having brunch with his mom tomorrow. She understands my POV.  I just don't know what to do anymore. Please, can anyone give me advice? Also, I know some medicine will make his mood swing. One time he almost put his hands on me. When I tell my friends whats going on, they tell me to leave. I really love this man, I don't want to give up, but our relationship is getting toxic.
