My wife and I split up six months ago. She checked out of the marital home and she found somewhere else to live. We rarely speak only about the children who live at home all older teenagers and mostly self-sufficient. She said she’d continue paying her half because she doesn’t want the kids to lose their house. However it’s starting to bother me how she comes and goes as she pleases. She doesn’t ask me before coming back she just shows up whenever she wants either to see the kids or sort some things out in her office. I have tried speaking to her about it but she doesn’t listen and just carries on doing whatever she wants. Do I have any rights to dictate to her when she can come back or not?
