Ian, She will not even talk to me so how am I suppose to set a schedule. I would love a schedule, but trust me her work schedule doesn't permit that.
That's not true Phil, a parenting plan can always be developed. Come up with one you believe to be fair and email it to her.
Quit making excuses and instead try and get something done. This is for your kids so her schedule, is meaningless. Figure out what your kids NEEDS are and implement a plan to make them fulfilled.
You and her....One issue....
The affects on your childrens day to day routine....more important right now.
