You can call me Gin :)
I only put the 'Sir' on so people would know I'm a bloke.
A lot of men are like that unfortunately, I appreciate it's frustrating if you can't discuss simple things about parenting like your dd's routine and all, but even if you could there will be hic-ups.
For example my Xp told me that she though dd was having more tantrums after staying with me. Part of me thought ' you're just saying that to put me down' , and that was a reaction that was based on our past which had no place in the present.
So I thought about it, and suggested that it was possible that as when dd was with me we didn't really have to be anywhere by any time, I'd always go at her pace. If she wanted to play with the car steering wheel I'd let her rather than strapping her in to her seat, if we went for a walk I'd patiently wait until she's finished looking at a flower or a bee or what ever.
However I understood that when out with her mum, they had things to do, places to be. So if they needed to get to nursery it wasn't possible to dawdle. And that I think was what was upsetting dd as she expected to be able to take her time.
The point I'm trying to make is that even if you could talk to your Xp there would still be things he does that you wouldn't do. If he can take her away for a week and they both survive, dirty hair, as unpleasant as it is, isn't a major problem in the scheme of things.
He obviously took your suggestion as interference. And he's a fool to.
I don't really know how you can improve communications. Massaging his ego possibly. Asking him for parenting tips ? ( I know I know but it might help ) Is there still a lot of bitterness between you about the past that hasn't been purged and discussed ?
I can only hope that over time he'll realize the benefit of good communication.
As for your confidence. Well, if it's been chipped away, maybe try and gradually build it back up. If he's not around putting you down it should come back anyway. Can you treat yourself ? I don't want to sound patronising but can you go and get your hair done, a new jacket, hat whatever ?
That generally improves my confidence.
