Biting lip - coparenting

[cocktailanddreams]

Been divorced a good few years now, DS has a good relationship with his Dad and generally everything ticks over ok. However, when I was married my Ex DH had an affair for 5 years and spent little time with my DS, however he was too young to remember. All DS remembers is the last few years of a kind and doting father, he knows nothing of what I went through as I know it would have a big effect on him if he knew the truth.

So I saw a message he sent his Dad saying he was his favourite (not sure if he meant parent or just in general), gushing on about what a great parent he is.

How do I bite my lip? I just want to blurt out the truth. It really hurts that I was the one looking after him whilst exDH was out having affairs and 'working away' for most of the time. Also, it doesnt help that his affair partner is his partner now and DS thinks shes wonderful too.

I understand OP.
While I've seen other threads on here advocating telling the child the truth (although I think that's always been when child's been older) i will always say it's better to say nothing.
And just let them have their relationship together as it is.
I get the hurt

It's not fair is it OP? You don't say how old your DS is, and also whether he is a good dad to all intents and purposes nowadays, or just a Disney dad?
I split up with my ex due to emotional abuse when I was pregnant with DS2. He has the kids every other weekend, but does the absolute bare minimum- on screens all weekend, junk food and takeaways, they don't go out and do anything unless one or other of his girlfriends facilitates it. The DC (especially DS2) love it. A whole weekend of screens and junk food, yay! 🙄 I had a blow by blow account of this brilliant meal Dad cooked them last weekend- wow, he actually cooked something for once!- pasta bake and salad, apparently it was the most delicious thing ever 🙄. (And there's me, who cooks from scratch every bloody night of the week....).
However, now DS1 is a teenager, I think the penny has started to drop with him a bit. You see, Dad can't be bothered to take him to any of his activities that fall on a weekend. Dad can't be bothered to take them to any parties or sleepovers they're invited to. They do realise, eventually....

DS is 11, so penny hasn't dropped for him yet, although generally he is a good dad, making up for his years of never being here.
Crackofdoom I completely understand that, it's so hard to watch and witness, very frustrating when they think they're wonderful.
