The way our separtion is NOW is he stays at his parents on days he works, on his days off he comes home at least one night overnight and I will leave and he will keep the kids at our house overnight.
The other days he has off he will visit if he wants to, spend the night at his friends overnigjt, at his parents, honestly have no ideabut 90% it is out partying, drinking, or hanging out with his single coworkers and spending the night at their houses.
It is a weird situation since we part time share the house so I have trouble with what boundaries I can make for the house.
