Please help!!

I’m 20 yrs old and I have a 22 year old boyfriend who doesn’t work and has a credit card that his mom gave him and let’s him buy WHATEVER he wants with it. The house we live in was given to him by his mom and she split the property we live on so she built a house right next to us so his parents are always right there and he refuses to move away from them and become independent. I’ve been with him for 2 1/2 years and ever since I’ve moved in with him I’ve been working 8-5 every weekday providing food for him and paying any necessary bills plus his car payment and etc. I spend more money on him than I do on myself because if I tell him “no” when he asks for something it’s the end of the world to him and he makes me feel miserable. I’ve gotten to the point where I’m $50k in debt and I can barely afford to feed us anymore. We’re relying on his mom to pay for food but I feel guilty every time and he doesn’t understand that asking his mom for everything he wants isn’t normal and it isn’t right. He’s told me to leave him several times if I don’t like the way that he lives because nothing going to change and he doesn’t seem to care that I’m drowning in debt because of him. I feel like I’m stuck because I love him but I’m unhappy being in so much debt at such a young age... someone please guide me on what I should do because I can’t do this anymore.
