Sharing older children 😓

Any other moms have older children who’ve decided they’d rather live with their dad? My kids father lives 40 minutes away as of this year. The kids decided they want to attend school at their dads house. I know they’re both are children but I feel upset because I’m use to our children being at both homes throughout the week because we use to only live 5 minutes from one another. Any other momma’s go through this
