6 Month Rule is a 2011 comedy film starring Martin Starr and Blayne Weaver.
The film follows "a womanizer and commitment-phobe" who tries to teach his best friend, a serial monogamist, the art of being single and how to avoid heartbreak.
Although he has published a book of his artistic work, he pays the bills with advertising photos.
Alan, Tyler's oldest friend, calls hoping to commiserate about the failure of his three-year relationship with Claire.
He scolds Alan for not recovering the engagement ring and insists he stay on his sofa.
Tyler's agent, Paul, calls him to meet the musician who wants publicity pictures.
It turns out to be at a gallery where the girl from the bookstore, Sophie, is hanging her paintings for an exhibition.
Six months pass and Tyler finally visits Alan in his new place and is surprised to see Wendy.
Variety said, "Script stumbles a bit, though, in a last stretch that caves in to sentimental genre conventions before halfheartedly ending on a semi-sober note.
