How hard will it be to explain dad’s absence to dc when they are older?

[Biopl]

What should I expect? Ex hasn’t been there ever. Not met dc once. Forced to paid maintenance. He has no other children and is still single as far as I know. Dc now 3. I am struggling with what I will tell them now and when they are much older. Will it really affect them? I’m so sad about it and have asked ex every few months to have a relationship with dc, he ignores me. I don’t think anything will change.

Be honest with them in an age appropriate way. Capture , acknowledge and support their emotions along the way, this will support them emotionally. Be their Mum , their solid constant and be strong and there for them. They will be fine , as long as they have you.

Oh.... and stop asking your ex to have a relationship with his child, his loss and let him reflect on that in the years to come. Not your burden to carry.

Many children these days are from single parent families. Quite the norm.
Wierdly my dds now mid 20's, tell me its almost a badge of honour at school.
Your ds will grow up surrounded by your love and care and he will understand who was the one who gave him so much and thank you.
