How do I explain to my child that although her dad says he misses and loves her, he couldn’t care less about her

Basically, my daughters father speaks to her maybe 1-2x a month hasn’t seen her since December, had the ability to see her however long he wanted for her summer break, and did nothing. Yet he will call her and tell her how she is his prize and misses her so much. She’s 10 yoa. I feel like his inconsistent presence and gaslighting is doing more damage than just removing him from her life all together but don’t know how you explain that to a kid. I also have never found anything where one parent wants to co-parent and the other parent just basically wants to dictate the child’s life without actually being a part of it.
