So in doing the 180 I told WW that if she is golng to start dating again then I would no longer invite her on trips out with my kids. I told her it's disrespectful of her to play happy families and keep company with me when she doesn't want me in her life anymore. She didn't like it and told me don't you think the girls would want their mom with them. I stood my ground and told her she can't be seeing other men and hanging out with me and my kids. That goes for vacations too.
That's fine but be careful that you don't cross over the line into using the kids against her. I completely understand not wanting to have shared vacations, but when you say things like "she can't be seeing other men and hanging out with me and my kids" they are her kids too and whether she's dating or not the kids need her and need their time with her as well as time with you. Don't deprive them of their mother no matter how you're feeling about things. Unless of course there's some kind of abuse, violence or exposure to drugs taking place.
