**IT'S A LONG ONE! But could use some feedback**

To start, my 7yr old son lives with his Dad during the week, and with me on the weekends (we have swapped a couple times prior due to jobs, my schooling, etc.). Since our breakup~7yrs ago, we have been civil, friendly, fair with split custody, sharing medical and daycare bills, etc. We even went to funtown with him, his wife and her kids. All of this with absolutely NO legal involvement.
