Let down by ex regarding contact with our son

[MyLifeInFull]

Ex last had contact with our two year old on Sunday. He said in an angry message to me Tuesday that he'd have him this Sunday (but didn't actually ask how he is). I've not heard anything from him but he has been away on holiday. Whenever we used to go away he'd always be in contact with his older children and their mother so I assume he has this time. It has really got to me that he is not bothered about him either to ask how he is or to arrange today. I don't want to be that mother who withholds contact but I don't want to wait around for his to click his fingers to decide he is ready to be a father today.

I know the mature response is to probably ask him but to be honest I'm fed up of chasing him to see what the plans are for contact. And when I do question it I get threatened that he'll go for 50% custody.

What would be the right thing to do here.

@HPandTheNeverEndingBedtime I understand that and thank you for sharing. I guess I expected to have the communication he had with his ex when his older children were younger. He always checked in, text, face time, rang etc. I just feel that he doesn't care about our son and doesn't do much for him. Hopefully it will change in time.

I have a 2 year old and DH is in the military so away a lot. FaceTime is pointless because my son doesn't care or talk to him. So to be honest he doesn't do it a huge amount. He will call to check in with me and we might talk about our son for 30seconds! Not much to update about a toddler! He's always called/FaceTimed his older kids daily but they actually speak to him. It doesn't make me worry DH cares about our son less. I would feel a bit awkward if I wasn't with DH to have regular contact involving a child who isn't receptive. However I agree contact plans should be pre arranged and more consistent.
