"I spend months – sometimes years – with the bride and groom. I get to know them personally, what they want to convey, what the bride wants, what her vision is. There's so much personal involvement in this."
At the wedding, Barronelle will often help greet guests and calm nervous parents. "When we get the bride down the aisle, then I know I've done my job," she said.
With floral arrangements for weddings being such a personal endeavor, she knew that she would be betraying her relationship with Christ if she participated in a same-sex wedding ceremony.
Over the last four-and-a-half years, Barronelle has received an outpouring of support – customers coming in to offer a kind word or a hug, strangers telling her they are praying for her family, and messages of encouragement from 68 countries.
But she's also received death threats. She's had to install a security system and change her route to work.
"Even today, we're very aware of people who come in who might do us harm," she said.
Also hard, she said, has been losing her relationship with Rob. She said she misses him and harbors no anger against him.
"I can tell you that if Rob walked into my store today, I would hug him, catch up on his life, and I would wait on him for another 10 years if he'd let me."
She also has a message for her fellow Americans: stand up for religious freedom, before it's too late.
"Don't think this cannot happen to you," she said. "I never thought that we would have a government that would come in and tell you what to think, what to do, what to say, what to create – and if you don't do it, you'll be totally destroyed."
"If we don't stand now, there will be nothing to stand for."
