Was she at her dad's for the periods when she wasn't at home?
I have the utmost sympathy for you as you deal with this difficult man and try to re-establish yourself as an individual after the experience of living with someone who likes to dominate.
My comments here are based on the experience of dealing with my own exH - please don't think I am having a go at you:
He likes to be informed about all aspects of their lives and is very involved in everything.
Normally society would pat a man on the back for such a level of involvement with children after separation or divorce.
However, in this case, it seems clear he is doing it in order to maintain the level of control he had while the family was a unit, and it is not healthy. You need to get stubborn here and try to break old habits, both his and yours.
You do not have to inform him about all aspects of his DCs' lives. If you have a court-ordered custody agreement, does it stipulate what matters he needs to be consulted on? If yes, then stick to that.
If not, learn to play your cards close to your chest.
Just because he wants the information doesn't mean you have to give it.
Both times she came home from school he got a text from the school on the “your child was not here for x,y,z lesson” system. He phoned and asked me where she was and I had to tell him. Just unwell wouldn’t have statisfied him.
So invent a plausible illness like vomiting or diarrhoea? You did not have to tell him exactly what happened.
Also, why is he getting texts from the school about absences? Who is the resident parent here? Did he insist on the school sending him every notification they send you? Is there any way you can quietly tell the school to stop notifying him if a DC has to go home for illness, or at least to stop notifying him if DD has to go home because of menstrual issues? Please approach the school and put your case to them that your DD has a right to a say in who gets to know about her periods.
Two weeks ago I had to run a fresh skirt up to her and he noticed she had her old skirt on that night, at that point I said it was getting ridiculous and I would take her to the GP to sort something out ie the pill or something else. The row has been rumbling on since, the links today about periods/hormones/the pill reminded me to ask on here!
You do not need to engage with him at all, on any topic. Don't let rows rumble on.
Say, 'Thank you for your thoughts,' after his first shot from the lip, and do not try to get his permission or agreement after that.
If you have a set idea in mind about how to tackle some issue, and it's not a life or death situation, he does not need to know and you do not need to speak.
I gather that DD was with him at the time he noticed her old skirt. This level of noticing details about DD is quite creepy. Please keep an eye on this, because DD is likely to find it makes her very uncomfortable. I strongly suggest that you seek counseling for DD as she tries to conduct a relationship with him.
If visits are not court ordered, I strongly suggest you keep an open mind as to whether DD really wants to go, and if she doesn't, then don't make her. Even if court ordered, please be ready to challenge the arrangement if she tells you she is not willing to participate any more.
You need to gird yourself to be a staunch advocate for DD (and any other DCs) as they get to the teen years. Very often a controlling individual ups the ante, and the teens perceive 'involvement' as more and more intrusive and see it for what it really is. Teens develop minds of their own and the dominator can't accept that.
Good habits to practice:
Do not think out loud when you are around him.
You do not need to have your ideas validated by him in order to proceed.
Practice this especially when it comes to your DD, and keep her privacy in mind first and foremost. She has a right to privacy here.
Part of the problem, as you well realise, is that he has conditioned you to run everything past him, and I suspect there is an unwritten basic assumption between you that he has power of veto over every single detail of your life and that of your children.
Just because he has dictated this or trained you to live under this rule doesn't make it the truth. Don't play along.
