Me and my ex split in March and my 3year old daughter has been having contact every Saturday since
But lately she has been behaving strange after her contact with her dad
He refuses to have her overnight because apparently he has better things to do
She has started having lots of mood swings and also very clingy and sensitive she doesn't seem very bothered about seeing her dad and seems glad to be back home
And since she can't yet talk very well I can't ask her why she is upset
I am beginning to believe that hap is a possibility
What should I do
