I have been divorced for 10 years now.my ex-wife and I have 2 boys.we never went to the courts to decide custody rights.we had a verbal agreement to have split custody and let either child stay with mom or dad.The first 5 years I had the 2 boys 3 days a week and she had 4.The last five years my 16 year old boy chose to stay with mom 6 days a week.my 11 year old stays 4 days a week with me and now wants to stay with me instead.we asked the mom about the possible change in schedule and she flipped out.she wants both boys 6 days a week.my 11 year old son is miserable and said will run away from home if he has to live with mom.what rights do I have.
