SOLVED. YA/older teens. Read in the early 90s. Teenager gets his girlfriend pregnant then gets custody. [s]

[Frankie]

A teen guy gets his girlfriend pregnant and then fights to get custody. He names the baby Mason and takes it with him to college. His dad is a professor. His mom’s not around (maybe deceased?) The girlfriend’s dad is a garbage collector. The guy moves in with girl roommates thinking they’ll naturally want to help with the baby but the girls aren’t at all interested. ... then he starts dating one.

Frankie, I see you just posted this request. I moved it to the "Unsolved" folder because you're looking for one specific book.
