So, I don’t have many clues. It’s not a new release, but I apparantly saw it about a year ago.
This guy is dating an older woman. The ladies ex-husband, who has a kid with the woman, gets jealous of this and comes to her house. The ex-husband wants to talk to someone but is acting very violent and ends up shooting and killing the guy. The rest of the movie is about the family grieving. At the end of the movie the guy’s dad kills the ex-husband.
