It all came down to one word: love.

After what seemed to be a romantic date in picturesque Barbados, The Bachelor‘s Matt Grant shocked Amanda — a woman he said “blew him away” when they first met — by not giving her a rose and a spot in the final two.

“It came down to the fact that Amanda hadn’t used the ‘love’ word but the others had,” Grant tells PEOPLE. “I don’t know if she’s really been in love before and I was thinking, ‘Can I really settle down with someone who hadn’t used the ‘love’ word yet?’ But also, you have to go with your gut as well.”

Matt’s gut told him to keep Shayne, a 22-year-old actress, and Chelsea, 25, a pharmaceutical sales rep. “My heart and head was saying it as well,” Grant says. “I knew Amanda wasn’t the one for me.”

This came as news to Amanda, who tells PEOPLE she’s still “confused” by Matt’s decision. “That doesn’t make sense to me,” says Amanda. “I thought I was starting to really connect with him and really get to know him on a more intellectual level as opposed to just the physical and fun side.”

While Matt ultimately didn’t feel a love connection with Amanda, he did hit it off with someone completely unexpected: Shayne’s dad, actor Lorenzo Lamas. And all it took was jam session to the Rolling Stones.

“We started singing ‘Satisfaction,'” he recalls. “He was just a nice guy, like one of my brothers. It was like being with one of my mates or something. We actually really hit it off.”

While Matt will chose the One on the season finale May 12, hear the stories from the bachelorettes left behind next week on The Women Tell All. –Eunice OhADAM LARKEY
