Just outside the entrance to the cemetery, talk to the angry woman there.
Walk up to the couple leaning on the fence right beside her. Possess both people and choose “broken hearted” as the jogging memory.
Return to the girl and put the three choices you have in order of “Broken Hearted, Ex-Girlfriend's Suicide, and “A Shoulder to Cry on”.
Once you do, return to talk to the girl and you will solve the quest.
