This house no longer feels like home

The initial passion has worn off and Dan, having become fed up of their new "domestic" breaks things off thinking it's best for both of them.
7 months later, Dan still regrets his decision. Phil continues to call on a nearly daily basis, but Dan is ignoring his calls, refusing to admit he's miserable without Phil.
Phil doesn't know what to do know Dan has left. He hasn't uploaded a youtube video for months, and has deactivated his twitter after all the questions about the missing PINOF video. When Dan finally answers his phone and reiterates that things are over between them, will it push Phil over the edge?
