My children’s father isn’t involved at all and has seen them a handful of times since we split up 5 years ago (in 5 years he has never had them for more than a few hours or even over night his choice) he hasn’t bothered with them since January and the last we heard from him he made it clear he didn’t want to be involved anymore and told me to “only contact him if it’s an emergency” which I have no intention of doing, anyway obviously kids ask questions and I want to be honest with them about why he isn’t around as I don’t want them to idolise him and build up a picture of him in their heads, I always don’t want him coming back in the future trying to twist things, aibu to be truthful when they ask?
