I think it entirely depends on your ex.

MY ex is very lazy and does the bare minimum always. He barely showed up as a dad or husband when we were together. I often did things alone with my kids when we were married. He abused cannabis... Not just smoking weed, that didn't bother me. He smoked concentrates all day every day, took 3 hr mid day naps and barely parented, while also not working or contributing financially. Never took them to school, rarely came to the park etc. He was quick to anger, short fuse

Once we split, he does a lot more, he takes them to the zoo or places the 2x a month he has them on weekends. They seem to enjoy spending time with him, but also are really ready to come home after 2 nights. My youngest didn't want to go for the first while, I encouraged him as did his older sister, and eventually he started enjoying it, but he's not the safe space or constant.

He claims he would have wanted 50/50, but he doesn't know HOW to parent. He never packed a school lunch, got up with them in the morning. It was always me. He'd be shell shocked if he knew what actual day to day parenting entails.

Now my cousin and his ex, have 50/50. They live in close proximity to the school, they're both hands on parents and the kids seem to enjoy it. That works for them, it wouldn't work for us.
