Monday night's (February 20) episode of the ABC show saw Ben travelling to the hometowns of his four remaining women - Courtney, Kacie B, Lindzi and Nicki - to meet their families.
In the end, Kacie B was the bachelorette sent home at the Rose Ceremony, meaning Courtney, Lindzi and Nicki will continue their journey with Ben to Switzerland next week.
Writing in her weekly blog for Ladies' Home Journal (which you can read in full here), former Bachelorette Fedotowsky said: "After watching Courtney and Ben tonight I really do feel like they're the best match for each other.
"Ben said it best - they're both a little 'weird' (I mean that in a good way) and they seem really comfortable together."
Courtney surprised Ben during their date in her hometown of Scottsdale, Arizona by arranging a mock wedding in which they wrote vows to each other, which they recited in front of an officiator in a fake wedding scenario.
Fedotowsky added: "Did you hear his 'vows'? I definitely think he's in love with her because he's never said anything like that to the other girls. I can't say for sure whether they end up together in the end, but I'd be willing to bet money on it at this point."
In his vows, Ben told Courtney: "From the moment I saw you, you took my breath away. What I asked myself after our first date was, is this too good to be true? The answer I found in Belize is, no. You are incredible. I love how to make me feel when I'm in your presence. You are strong, kind and beautiful and I find myself falling for you more and more every time I'm with you.
"You are real and honest. Thank you for believing in me, and trusting that we would get to this point after an incredible journey."
Ben wrote in his blog for People that it had been a "bold move" on Courtney's part to plan a mock wedding and assume he'd be happy to go through with it, but said it was worth it because it gave her the chance to tell him how she really felt.
"Hearing Courtney tell me she loves me made it all worth it. All in all, it was a great hometown date and a great way to conclude visiting all of the hometowns."
The Bachelor airs Mondays at 8/7c on ABC.
