My kids 'dad' lied to them, again. It's an ongoing thing with him, he has a serious image issue and always needs to look like the good guy, great father etc... He's a very deluded narcissist. An example: In my home you are asked to cough into the crook of your arm, especially when sick. He knows this rule, I remind him every.single.time he's here as he's always sick (clubs a lot even at 37 years old). He's here visiting them now, today he keeps repeatedly coughing into the air. I say to him "Please cough into your arm, I'm getting tired of reminding you. The children have better manners than you do" his reponse "I did cough into my arm"


Now to the question.
He had told my kids he'd come for christmas, then his visit about a month before christmas my 7 year old was talking about it and he says "I have to spend xmas at my moms now, she's old and her health isn't great" my youngest begged otherwise but in the end she understood and was as okay as she could be with the situation.
The problem. He did not spend christmas with his mom. He spent it with a woman he's seeing and her daughter. He doesn't realize his friends were my first first and I'm told everything he does without asking. I don't give a crap what he does, and personally rather he not be here over christmas as I can't stand him, but I put up with it as best I can for my kids.
I have spent YEARS covering up his lies and keeping his good guy image up for him in my kids eyes, as to not hurt them, while giving him a chance to get his priorities straight... all the while I would and still do tell him exactly what I think about him etc... I'm never bit my tongue when dealing with him.
I've slowly started letting go of the noose and leaving it up to him as to whether he will hang himself with it or not. I still cover up with things he does that would be extremely hurtful to my kids. I'm tired of it and I don't want to do it anymore, I never did want to do it and I certainly do NOT do it for him. He could get hit by a ######6 bus tomorrow and I wouldn't give a $#%^.
I talked to my mom about this and 1 'friend' who knows about my AsPD diagnosis and they both asked me if I'm wanting to let my kids know all the truth for my own self serving reasons... which got me thinking. I know I would like it very much for my kids to see him as the piece of $#%^ he is, so they'd not want anything to do with him hopefully and then I'd not have to deal with him.
On the other side though, would it not be good for them to start seeing him as he is? Should I be covering up his lies? Supporting them in front of them when I know the truth? I want to throw the rope at him and let him hang himself with it.
Which is more detrimental to my kids (9 and 7 year old girls), letting them see him as someone he is not and support his lies, or tell them the truth and let him ###$ himself over? Somewhere inbetween?
I want to do what's best for me, but I need to do what's best for them. I have no clue what the 'right' thing is in this situation and my self serving wants cloud my judgement.
