AITHA for breaking up with my boyfriend after what he mother told me?

Hi Reddit. I am new to this. And just needed advice outside my family and friends.

So I (f23) have been with my boyfriend (m24) for 3 years. I love him. We had an amazing relationship where we both supported each other in everything we did. At least I thought we did until I meet his mother. (The reason I haven't met his mother until recently was because she lives out of state and we didn't have time to.)

Anyways the first time I met his mother, she asked if I was taking care of her boy. Like feeding him,doing his laundry, cleaning our house. And I said yes I am. Mind you I'm working 1 job while going to college.And I come home and start Cleaning. While he is just playing video games or taking a nap.

She asked me if I was a stay at home girlfriend. I said no I'm not. That I have a good paying job and going to college. She told me I should drop out and quit my job to be a stay at home girlfriend I said no. I really want to become a lawyer and I need college to do so. She looked shocked and told my boyfriend he deserves better then me. He didn't argue with her and agreed that he deserves a girlfriend who is a stay at home girlfriend.

Later that night, I broke up with him and moved out the next day. He asked me why I broke up with him and I told him he deserves better then me apparently. He told me I was making a big deal out of nothing and I said okay whatever. I cried that night to my sister and got drunk.

His family is thinking I overreacted and broke up with him for no reason my family is of course on my side. I didn't make a big deal out of it. Just said we are over packed my stuff and moved out. But now I need to know if I'm the asshole?
