And you got sucked in again! The minute he started speaking about OW you should have cut him off...I have my ideas of why he did this but what good it does you I don't know...
Also, you should not have questioned your D...kids start feeling "caught in the middle"...she didn't tell you because she didn't feel comfortable...it would have been better to bring things up in a "what if" sort of way...ease into the discussion of things like that and let her volunteer to tell you based upon your easy feelings about things...
All I can say is he is slowly roping you in...getting you to talk to him...asking your opinion...I can hear the fishing reel being wound up...can't you see it???
