"He just texted me and was like, 'Hey, Mom, I'm not coming back,'" she recalled, before her mom-mode activated. "I couldn't even believe it. At first I'm like, 'I'm coming up to Alaska, we're not doing this.' I was so mad."

However, over time the Teen Mom OG alum accepted his decision and said the pair remain in close contact while they're apart.

"I respect that he thinks this is what's best and he needs that relationship with his dad," she said. "Selfishly, I'm like, 'I just want him with me forever.' He's my best friend. My kids are my whole world. But I can't be selfish in that."

Bristol took to Instagram to share a first day of school photo featuring her daughters Sailor Grace, 8, Atlee Bay, 7 -- whom she shares with ex-husband Dakota Meyer -- before revealing that her 15-year-old son had moved back to Alaska.

"This has been the hardest 'first day of school' yet with one of the biggest pieces of my heart missing," the 33-year-old wrote on Instagram.

"Tripp has decided to finish out high school in Alaska to be closer to his dad and our entire family."

In addition to being closer to his dad, and Bristol's mom, former Alaskan governor, Sarah Palin , Bristol said that her son's passion for hunting and fishing largely influenced his decision.

"As hard as it has been to come to grips with his decision -- it's truly not about what I want," Bristol said. "He's almost 16 years old and that relationship with his dad is a lot more important than my own selfish desires of having him with his mama forever! I can't talk about it yet without crying, but selfishly praying for a quick year and easy transition for us all."

Bristol moved to Texas from Alaska after marrying Meyer and stayed in the Lone Star state after their 2018 divorce for the sake of her daughters.
