No point.
And I honestly think you are getting to the stage that you would all be better served by letting this prick be the misogynist, entitled, dunderheaded wanker he clearly always was and let him go ahead and show time and time again who he is, until your daughter walks away emotionally too. Frankly, it would do her a favour.
Having read your threads, it's been noticeable that out of your children, your son is more unscathed. Do you realise yet that that's because he's probably spent your children's lives relating to them differently, based on gender? He's a womaniser, a 'charmer' - a person who is so deeply misogynistic he truly believes that women are some lesser species that good old red-blooded men like himself can pick up, put down, shag, marry, lie to and whatever they want, when they want. And he can't even now see what's really wrong with that.
So, your son, who he has had no option but to be kind of straight with, has simply walked away. Your daughter, who has been charmed, flirted with, had her behaviour 'mirrored' back by him all her life (you used to comment how 'alike' they were a lot) has now been treated just like all the other women in his life - completely dismissed, wilfully misunderstood, and is now as let down as you and as OW soon will be, by Mr. 'I was confused! What did I do?!' That's the way he treats women: that's the way your daughter has been treated too. He's respected your son's boundaries, hasn't even dared approach them, but your daughter's are to be negotiated, trampled, charmed away. Lip service, because she's only a woman.
I think it would be good if you saw this as the real alarm bell it is: having a father like this is the LAST thing a young woman working out male behaviour needs. Let him show her that he is a shit. Because he IS, don't think that trying to make him look like not a shit is going to do her any favours. If you want her to have healthy relationships with non-womanising men who listen to what she says and see her as more than a fluff-headed vagina on legs, let her see what her dad is and DESPISE him, even if she eventually makes peace with it and can love him.
So bring on that jointly signed card.
