Katie Musser has won the Internet after marrying her husband Jeremy Musser and giving vows to her stepson during the wedding ceremony.

Katie and Jeremy started dating in 2013, just before she found out he had a newborn named Landon with his former girlfriend. But as their relationship grew, so did her relationship with Landon.

This September, Katie and Jeremy got married and in a Facebook post, she shared the memory:

“I wasn’t just going into a marriage with Jeremy and needed his trust and respect, but I needed Casey and Tyler’s too. One thing I promised was to be ONE family always. And I know without hesitation, we will never break that promise,” she wrote.

“First I want to thank you for accepting me as your friend and allowing me to be a part of Landon’s life,” she said in a video. “I promise to be an amazing mother to your son. I will guide, teach, and love him every single day.”

Katie then spoke to Landon: “I promise to stand by you, listen to you and love you every day. I promise to love Daddy with all my heart. I promise to be a best friend to your mommy and your daddy Tyler. We will be one big family that I promise you will have for the rest of your life.”
