My ex has our 3 children every other weekend and half the school holidays this has been the agreement for about 18 months. About 2 months ago he and our eldest who is 15 asked me for extra time together and I reluctantly agreed to let him have him from the Thursday to Sunday of his weekends meaning that the youngest 2 join them on the Saturday morning until the Sunday night when I get them all back. This week I have found out that my ex has let my parents (who I am estranged from) have our son for his extra 2 days a fortnight and not spent that time with him anyway. I feel like I gave up some of my precious time for them to bond and they haven’t spent it together anyway. Can my ex do this? We have no court orders in place.
