I thought about this some time ago. They're probably your average retired, middle-class boomers who care for their only son but are surely aware of what a fuckup and loser he is. Granted, they only get their perspective on Phil's life from Phil himself (who's obviously gonna lie about a ton of shit) - but there's no way they don't worry in private about all of his obviously terrible decisions. Phil's father seemed to make a genuine effort to shape Phil into being a normal, functioning, independent man; he got him an actual job, got him an accountant to handle his taxes, helped him move, and, I imagine, advised him on just about everything else (his car, his relationship, his spending, etc)
What must they have thought when they heard Leanna dumped him shortly after the proposal? I can't imagine they're surprised. It must be a shitty feeling being a parent and owning a guy as childish and loathsome as Phil is. Do you think they look him up online? Have they heard of the fapping videos, and all his e-begging? In my experience, most mothers will dote regardless of what a garbage person their kid is, but his dad must be extremely disappointed in what a pathetic, shameless, incompetent excuse for a man Phil grew up to be. There's a certain disgustingness to Phil's existence and attitude that I'm certain they've picked up on and are aware won't change.
It's very surprising to me we don't have more information on his relationship with them than we do. There probably isn't much to discuss - he treats his parents like living ATMs, and they consent because they feel a paternal obligation to their gouty-spawn.
