My dh's ex would blame him for everything that went wrong to the dc's, tell them he didn't love them, he hated them etc and though he was giving money and paying for the house she would worry them about things like telling them there was not enough food in the house (but apparently enough to get new boots and a manicure).
So my dh went around and sat them all down in the living room with her there, and explained the situation, that he loved them but that he didn't love their mum any more and that they would be happier apart etc. She couldn't get out of it, and would have looked stupid if she started all the nonsense.
I know you are in a different situation, but I wonder if you should do something similar, so they know what is going on, that it will be how things are, and if they have any questions they want to ask you both?
then he can't squirm out of it, you look in control and you do it calmly? And then they also get an opportunity to ask some questions?
I know it doesn't work for everyone but he is shirking out of his responsibilities.
Oh and tell him that you don't need a blow by blow account of his sordid love life. If he has time for his dc's then fine, but fgs you don't need to know the sad detail of his failing dating life. And remind him that he is still married and should try to carry himself with a level of decorum that befits his advancing years especially around his children.
Not fair that he seems like he is boasting around you. Does he want you to be happy for him?
Sorry where, but I could shake him for you I really could.
Hi Bella, hi fire hope you are feeling better?
