How to obtain Callum's good ending?

I have tried and tried and tried...but always end up with a bad end...

Callum's route is locked at first for plot reasons, so if you haven't finished some other character's route first you will not be able to get to him.

After completing another character's story, start the game over and during the scene at the river, an option to talk to Callum will appear that wasn't there previously. You'll need to speak with him there in order to start moving towards his route.

If you've gotten onto his route already but keep getting the bad ending, try different approaches to handling his family problems.

Someone's also posted a guide here that might help: http://steamcommunity.com/sharedfiles/filedetails/?id=453668292
