When is the right time to talk about marriage (Kinda long, but hear me out please)

My mom sat me down yesterday and told me that I need to talk to my boyfriend about where our relationship is going and if he sees us getting married in the future. And if he doesn’t want to marry me, I should break up with him now. Pardon my french, but I think my mother is absolutely bat s*** crazy and it’s started a huge fight. Here’s the thing: my boyfriend and I have been together for just a year. I just turned 20 years old and he’s turning 23. I’m still in college and he’s unemployed trying to figure out what to do with his life. I don’t know much about men but I’m pretty sure talk about marriage would make the typical young guy RUN. Now, he’s never come out and said “I want to marry you”, but he has, several times, hinted at us being together for a long time which I think is a good sign. My mother, being her crazily religious self, had said that over her dead body would I live with him without being married first. She says this is “living in sin” (Oh no!)

I don’t feel the need to ask him if he thinks he’s going to marry me. If in the future we decide to live together, then yes, I will ask if he sees the relationship progressing further. Am I in the wrong here though? SHOULD I be asking him where the relationship is going? I think the biggest thing is that my mom is worried that I am wasting my time and she doesn’t want to see me hurt. I understand that. But I just think that asking him about marriage might make him really uncomfortable. I don’t know. How should I approach this situation?
