family dramedy set in the 90s

I can only remember a few details. The dad was played by a fairly well-known actor, and the lead female found poetry or writings from the dad on a floppy disk. The dad and mother are having relationship troubles. The younger sister I believe was sneaking around with a friend that she is sleeping with. It was a modern movie I believe made in the 2010s or late 00s but is set in the 90s or maybe late 80s
