Please have confidence in your convictions.
You’ve posted as if you’re doubting your own mind. You seem to be able to detach from your feelings which is probably something you’ve learnt growing up but it’s not helpful in this situation.
I think in order for this relationship to work, you need to recognise the enormous challenge of bringing a partner into your family and how that can be done successfully.
I can’t stand the term “the ick” (sorry it sounds so childish 😬) It’s better to honestly examine your feelings and where they’re coming from.
Do you feel disappointed in your partner for handling a situation badly? Do you feel undermined / judged as a parent? Do you disagree with his approach? Think he’s trying to be a father figure and getting it wrong?
You need to put your big girl pants on and communicate with him how you’re feeling and what you expect of him.
In order for this relationship to work, you need to both be adult about how this man can fit into the family.
You need to make your expectations clear to him- he may be floundering with it too- unsure of his “role” in relation to the kids.
Its best to work slowly- make it clear that in front of the dc he takes your lead with parenting. He can back you up, you can present as a team but it’s too early for him to be making parenting decisions or for the dc to see him as anything more than mummy’s friend.
That said, If you teach your dc to ignore everything your dp asks then they’ll quickly learn to play you adults off each other.
Make your expectations clear to dp and don’t leave the parenting down to him- it’s far too soon. Have these discussions away from the dc.
He can bring up issues he has with your parenting too if he’s prepared to be respectful to you but do that away from the dc.
He’s gone from a carefree single guy to suddenly a parent of multiple children and probably doesn’t have a clue what’s needed of him.
It’s normal to hit stumbling blocks when you’re introducing a man into your family and trying to blend. You can’t force it but you need to put a lot of effort and communication in to make it work.
The worst thing to do is put your head in the sand and hope these issues go away on their own x
