Ah! I'm having partner issues what do I do?

Co
I am currently struggling with my partner. Usually we're on the same page, but for the past couple weeks he has mentioned that it is "embarrassing" for him to tell people I am not going to college. I work, and I'm currently saving to be able to move to a different residence, so I'm not entirely sure why he'd be embarrassed since I'm DOING something. 
Anytime I address the issue and that he makes me feel under appreciated and hurt he exclaims that he "doesn't get why I'm on the offensive". I've never considered myself a failure for not jumping straight to college after highschool.
 I can't afford to, and while his parents are willing to house him, give him a free car, pay for his gas and food while he goes to college, my parent is not. I have to work and save if I intend on accomplishing much. I point this out to him on occasion and he says that I am in no position to talk about his family and how it works?? 
I don't know how to talk to him about this. Is there any advice out there? He's never been a braggart so I don't understand why school is such a huge issue for him and why it'd be "embarrassing" that I'm not attending right away. 
I'm not expecting any responses😅 but I suppose I needed an outlet for once haha.
