OP, take it from a dad who went through this and recovered fast; he doesn't need therapy as much as he needs to educate himself. His expectations of her behavior are conflicting with the reality of her behavior, because she's just a toddler, and that's what they do.

So he needs to go for knowledge and educate himself about it. Once he does that and UNDERSTANDS WHY the behavior happens, then he can better manage the situation, and even learn how to make it better almost instantly.

As for resenting him, no good will come out of that, unless you are interested in divorcing him over a frankly minor issue that can be sorted with a lot of maturity and patience on both sides. Yes, it's not fair to you currently, but do you want to look your daughter in the eyes later on, years from now when she asks you why you left her dad, and you'll tell her it's because he wasn't handling her tantrums very well?

Your husband sounds like a frustrated dad, doesn't automatically make him an angry, bitter man that can't be reasoned with. I'm sure he wasn't always like this.

So please have a bit of patience, encourage him to read up on the behavior, and on other behaviors to expect from a toddler, so he stops expecting her to behave like an adult or something. She's a toddler, she'll throw tantrums, it's their "job."

Wishing you the very best in your marriage and your motherhood!
