"I have stopped being comfortable at all living by myself," said Coulter.
After suffering a serious seizure, the 50-year-old found out earlier this month that her lung cancer had spread to her brain.
Coulter lives in a two bedroom Section 8 subsidized apartment and asked housing officials if her friend Pam Koo could move in as a fulltime caregiver.
She was told no and says officials instead suggested 12-hour shifts using outside aides.
"Why take a stranger that's going to cost Bucks County a ton of money when I've got someone who's so willing to move in here and do it for free?" said Coulter.
A former pharmaceutical lobbyist, Koo lost her home and her job in the recession and is now homeless.
She sleeps in her minivan at night. By day, the former hospice volunteer cares for Beth, keeping track of her appointments and medications.
With Coulter's condition declining and afraid to stay alone she started asking for help and appealed the Housing Authority's decision.
Coulter contacted the media and several politicians including Senator Pat Toomey's office.
Tuesday morning, Action News learned that the Housing Authority has reconsidered and is now allowing Koo to move in.
"I'm very very happy," said Coulter, when she heard the news.
A mother and grandmother, Coulter says she doesn't know if she has six weeks or six months left to live but at least now she can relax.
"Now that it's okay, I can live happy and I can die happy. That is the only thing I'm concerned about," said Coulter.
That sentiment was shared by both.
"This is such terrific news and it takes a lot of stress off of her," said Koo.
Koo will have to go through a criminal background check and fill out paperwork before everything becomes official.
The Bucks County Housing Authority declined to comment on the reversal of its decision.
