Yes, I am angry and sad with him being this way with our child and blame the child's misbehavior for his anxiety and rage.
I think you need some acceptance and patience for how your partner is.
I don't see it as "blaming the child" so much as he just doesn't like it.
He has a right to feel anxiety and rage over a misbehaving child.
Maybe he needs to express that anxiety and rage differently but if you try to make him suppress it you will literally be creating a SarnoTMS situation.
A child misbehaving IS rage worthy. But still as a parent you need to find ways to accept it.
Personally I don't think your partner is going to learn to not have the rage and anxiety about it in the amount of time that the child will be a child.
So instead of working on that, I'd working on a plan for what to do when the child misbehaves and your partner is pissed off about it.
He will have to accept that the child is going to misbehave because that is what children do.
You will have to accept that it is going to bother your partner and that you are going to have to be the one handle the child in these situations.
If you are both willing to accept those two things then you can work it out.
If he will not accept that it will happen, then it will not work out.
If you will not accept that you will have to take the burden during the child's younger years, then it will not work out.
This may seem like a dumb example but I'll say it anyways. I mentioned that my husband is very similar to yours.
We have a new puppy. A puppy is even more misbehaving than a child. And that includes bites and scratches. It's what puppy's do while they are learning.
My husband doesn't like misbehaving. And he also doesn't like being the adult. He doesn't like being the bad guy. He wants to be the puppy's friend and of course gets mad when the puppy misbehaves because of that.
I have to do the training. I have to be the bad guy with the puppy. I have to be the one to stay calm and smooth things out.
And you know what? So what?!
When I was younger I'm sure I would have been upset and tried to fix the situation. Fix my husband for not acting like an adult and the leader that is required when you have a puppy. I'm sure I fretted about it with our last puppy though I only slightly remember. Now that I'm older and wiser, I realize that you pick your battles. I will take on the burden and I will not resent him for it. (well, maybe I will journal and want to beat the shit out of him for a couple of minutes).
I have nobody to rely on if I need a break and recharge for a while
If you take on the burden most of the time, you will be in a good position and so will he to take on the burden every once in awhile as a special favor.
You'll be able to say --- "I know you hate it but I really need a break. Can you take over for a couple hours while I go do xyz? I really need that break."
I know my husband would respond to that, even though in the daily scheme of things if having to do so all the time he would be going crazy.
Good luck. Raising children (and puppies!) is hard work.
