My ex has stopped contact with our almost 3 year old DC, 2.5 weeks ago.
Today they brought him up properly for the first time. They said ‘im sad because daddy isn’t coming back to get me’ 
I think the wording is because he used to pick DC up from nursery most days.
I feel so sad and heartbroken for DC. I don’t know how to explain it to them.
They used to be happy going into nursery and being cared for by other family members, but now they cry at any separation from me and are really clingy - nothing has changed in our routine except the lack of contact from their dad so I’m fairly certain that’s the reason.
It looks like he’s really cutting contact for good. I’m not sure how best to explain it to DC and support them. If he cuts financial support I’m going to really struggle with money.
