Dating a mamas boy?

Okay ladies, I have a question. My boyfriend is a HUGE mamas boy. And tbh I'm quite tired of it, it can't stand it.

He pays half the bills in her house even though she has a boyfriend. She doesn't work, doesn't have a car, doesn't do anything but bake cakes all day long. She claims she's starting a business but never shows any real effort for long. It's always something she throws out there when we says she need to get a job. She has management experience, she has TWO degrees, and is a public notary. So it's not like she CANT work. She's not disabled, mentally ill, and she's only 51.

Yet my boyfriend still pays half of her bills, lets him drive one of his two cars when she pleases, and expects me to help her out as needed. He had a GREAT paying job, but still has to live pay check to pay check because of the money that goes towards her household and expenses. He sometimes has to work 7 days straight just to make sure he has enough money to help her. Which if course his health takes a toll. He suffers from migraines, which is often triggered by lack of rest. And who's left to care for him when that happens? Me. Sometimes we can't go out on dates or spend the money how we want to spend it Bc he simply doesn't have the money. I'm currently a rad tech student and I work for my dad. He has his own business. I'm also a mother, my son is two. So I'm focusing on school so my finances go to my own household. But I'm actively working to get a better lifestyle.

I feel that his mother is using him, and takes him for granted. I mean why would she work if they take care of her the way he does.

Do you guys feel I have the right to be upset?
