Am I asking too much ?? Or what am I doing ??

I’ll start with a backstory .. my boyfriend and I never graduated high school . He has a learning disability but knows his way around fixing transmissions and fixing vehicles .. I just . Got pregnant and dropped out and never went back. We have a 7 year old together .. my boyfriend adores our son and my son prefers to hang out with his dad all the time .. I told my boyfriend the other night I don’t want our son to be like us.. and he was like “what’s wrong with that”? .. I told him in a roundabout way that I want our son to graduate and go to college . And we started arguing .. in the end I hurt his feelings I know I did .. because when he chooses to be alone and sit in his truck all night I know it ..he’s the mechanic making twice what I make .. and I’m just a cashier .. but I would like for us both to agree that our son deserves more then what we both are .. idk.. maybe I should just shut up about it ?
