Can't force someone to parent. She uses work as her crutch that she works a lot. She is in the Army but so was I. And she's screwing her boss. But can't make her show up and stay with him
No. But you CAN work out a schedule. If she wants to be a parent, arrange something you both can agree on. Dont let her just waltz in, parent a couple hours when it's convenient and then leave.
