My wife wants to re-watch a movie and her memory is just vague enough to fail my Google-fu:
Three separate storylines of three family members, and they all invite their new boyfriend or acquaintance or employee to a family gathering, and at the end it turns out it’s actually all the same guy.
She watched it sometime from 2008-2013, and the movie itself is unlikely to be too much older than that.
Halp!
Crazy Stupid Love?
She says no on that one. I thought it sounded right, but I guess not.
I can only think of two family members (husband and wife, the 3rd player being the mistress of the husband), but it sounds like “The Secret of My Success” with Michael Keaton living a double life. Came out in the 80’s I think.
In Good Company has Dennis Quaid invite co-worker Topher Grace over for dinner, with Quaid’s daughter Scarlett Johansson as Grace’s love interest.
