Sean Lowe and Tierra on The Bachelor
No regrets? Not so fast.
In his PEOPLE.com blog, The Bachelor
's Sean Lowe has written about how he never saw
Tierra LiCausi behaving badly – despite what the other women told him
about the controversial contestant
, who is now engaged
But after watching, Sean realized the women were right.
"Man, I was such a fool," Sean, told host Chris Harrison on Sean Tells All
special Tuesday night. "I really do feel like I was duped."
In fact, Sean, 28, who had an immediate connection
with Tierra, says he never should have met her that first night.
"Tierra never should have come on this show. She's not suited for this show," he said. "She doesn't know how to handle herself in this environment. She's a woman who ... simply can't get along with her peers."
Not only did Tierra waste his time, Sean says, he witnessed her "getting into arguments and fights with the sweetest, best people in the house."
But no one may be more upset about Tierra than the women who was sent home instead of Tierra, Jackie Parr, on a two-on-one date in Montana
I wouldn't have kept [Tierra]," Sean said on Tuesday's special. "I wish I would have kept Jackie on the two-on-one."
