Thanks guys, I know it will get easier after the first meeting.
I saw my oldest last night at soccer practice and she had a complete meltdown on the way home as I was talking her to her moms place. What started off as her being upset with something that happened at practice ended up with her telling me she did not do good on a math test and was afraid that her moms bf was going to yell at her. I then followed up and asked her what happened and she said I didn't know what 9x7 was and he told me I should know that.
I told my xw what she said and the x came back to let me know it was not a big deal and explained to me what happened. I guess I just have to trust her as there is not much I can do. It also sounds like to me she is allowing him to actively help her raise them. Imo he is just a bf and shouldn't be in that position, a position of doing something to make my daughter feel a certain way.
