Bride Makes Emotional Vow to Stepson and His Mom During Her Wedding Ceremony

There wasn't a dry eye in the room.

A Pennsylvania bride took a moment at her wedding to not only recite vows to her new husband, but also to her stepson and the boy's mom.

Katie Musser, 24, said it was important for her to include everyone because they operate as a family.

“For a long time, I struggled with people asking me why I get along with her or why I would do that to myself,” Musser told InsideEdition.com. “Regardless of whether people accepted it, I needed to let people know how much they mean to us.”

In a touching video shared of the moment, Musser turns to thank her stepson’s mother, Casey Bender and his stepfather, Tyler.

“First I want to thank you for accepting me as your friend and allowing me to be a part of Landon’s life," Muller said to Casey during her September wedding. "I promise to be an amazing mother to your son. I will guide, teach and love him every single day."

She then turns to her stepson Landon, 4, and bends down to tell him how much she loves him, followed by a big hug. Nearly all the guests could be heard crying during the gesture.

Musser said the moment was a complete surprise and that she hadn’t told anyone in advance.

“No one knew that it was happening, not even Jeremy. Casey cried the entire time. It hit her hard,” Musser said.

Musser said she has been dating her now husband Jeremy, Landon’s father, since Landon was born in 2013.  Although there was initially animosity between her and Landon’s mom, she decided one day that their relationship needed to change.

“It was kind of typical," Musser said of her relationship with Casey. "We both believed all the rumors that people said and then one day we decided it was time to grow."

The emotional video has been viewed nearly a half-million times on Facebook. Musser says she hopes the video is an inspiration to others.

“I wanted others to see that it is possible co-parent regardless of the situation,” Musser said.
