A short lived engagement 

Peter Weber is speaking out on his whirlwind romance with Bachelor costar and season winner, Madison Prewett.

The finale, which aired Tuesday night, showed the 28 year-old pilot ending his engagement to Hannah Ann Sluss.

He reunited with his runner-up, Madison Prewett — and fought with his mom, Barbara on live television over her disapproval of the change.

On Thursday night, Weber spoke out after all the drama in a message posted to Instagram, and revealed that he and Prewett have decided to split!

“Madi and I have mutually decided to not pursue our relationship any further. Believe me this was not easy for either of us to be ok with, but after a lot of honest conversations, we have agreed that this is what makes most sense for the two of us," Weber wrote.

“Hannah Ann, you set an example for women everywhere a couple nights ago. You are such a strong, confident woman and you deserve all the love in the world. I accept full responsibility for my mistakes in our relationship and wish you only the best,” he continued.

“This has been an emotional experience and I am so grateful for the outreach of support that I have received from friends, family, and Bachelor Nation in the last few days."

Prewett shared the news as well, writing on Instagram, “As Peter and I have decided to go our separate ways, I am confident that we will both move in the direction of our purpose and never forget that God has a plan in all things. I will always love and respect him."

Weber's mother said on the finale that their relationship "wasn't going to work", and that Prewett left a bad taste in their mouth following their Australia meeting.

In an interview with Life & Style on Thursday, Barb declared that she won’t try to make amends with Madison. “There’s nothing for me to apologize for,” she insisted.
