Lone parent, DC asking why dad isn't here

[Belle96]

Hi all,
Hope you can help me, I have a wonderful DC who is nearly 10 years old.
Myself and the dad split at 15 months. He was emotionally abusive and never followed on with wanting contact.
I have done everything since as you would, I did meet another partner and I've since had another DC now 4, however again the relationship wasn't the best split before they turned one and no contact again.
My lovely DC is obviously questioning a lot right now which is fine but we've had such an emotional discussion tonight about his dad, I've always done it in a child friendly, they weren't ready etc
So now its a case of but I'm ready why can't you find them.
I cant find them in adult terms they're not bloody interested never have been and never will, I have no contact details for them and no means of finding this unless I can hire some sort of person who would do this but as a lone parent to two I don't have the money for this.
I dont even know where to go with this right now.
Can anyone advise, even if its just a more child friendly way of telling them it's not going to happen?

What is it you actually want to know?

Be honest and say you don't have his contact details so have no way of contacting him.

At your son’s age, it’s important to be honest because he’ll remember the explanations given.

I would say that the relationship broke down as you and him didn’t get along and he changed his phone number because he didn’t want to be contacted any more.

If you’re blocked on ex’s social media or he moved away after the break up then you can add that as reasons why you can’t contact him.

Maybe social media point isn’t good because you don’t want him to try and find ex on the internet. Hopefully ex will have a profile that isn’t his actual name so hard to find.
