Love's Complicated (2016)

Leah thinks all is fine coasting along in a relationship with the ever-predictable Edward until he surprises her and enrolls her in a conflict-management class. In the class, Leah finds herself locking horns with a handsome, radio talk-show host who thrives on making waves. Through the course, Leah develops new friendships, an inner strength she never knew she had and discovers real love should never mean settling for the easy and predictable.
