If your D12 is asking about her mother dating anyone.......and she's overheard a conversation between Mom and OM, then she probably wants it verified. Her mother could be lying to her, but you don't have to cover for the WW and OM. Your D12 will appreciate you being honest with her. If you try to cover to "protect" D12, she'll know it and then she won't trust either parent.
Don't try to tell D12 how she should feel. Allow her to be angry at her mother. You don't have to talk badly about your WW to D12, but be honest when answering her questions.
In most WW cases I've known, she has a hidden agenda before she ever leaves her H. All this business about not being happy, etc., was just her excuse to get out of the MR. She did not leave in order to work on the MR. She probably planned to tell people she met OM later.......and maybe she did, when she was out behaving like Girls Gone Wild. If your WW gets angry that D12 went to you for the truth (and she probably will), just tell her you will not cover up about her boyfriend. That doesn't mean you should get on social media and announce it. But neither should you lie to keep it a secret.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
