Hello,
It could be seen as positive that he wants to go on holiday with you and the kids. Perhaps he does really want that time together with you. However, it's not really fair for him to put all planning on you and then not be happy with what you suggest. Plus, for him to be not communicating much about anything else, just seems unfair.
What do you want to do? If you think it's workable to go on holiday with him, you could ask him for suggestions. Or you could give him some general options and see which one he picks and you could finalize details. But just to let him sit back and not do anything and then complain about what you do is not fair to you or to him. It's kind of like a spoiled child who has been indulged too much and isn't happy with anything.
It might help for you to figure out what you want and be more decisive yourself, in regards to where you'd like to go, if you'd like to go, and then tell him what you were thinking and ask if that sounds good to him. If it doesn't sound good to him, you could tell him you're open to suggestions. If he gives none, you should feel free to make the decision on your own for what you'd like to do.
Honestly, it's very rare when my h will suggest plans to do something. Usually, it's me who makes plans and tells him what they are. If it were a holiday, I would consult him, ask opinions, but in general he is very indecisive.
You can't please someone who doesn't want to be pleased. If you asked him and tried to nail him down, but he doesn't give you a straight answer, you are left with no choice but to make a choice on your own.
I hope you have other connections and people you can talk to. Silent treatment is its own special form of abuse. It drives me nuts, which I'm sure my h knows so he uses it often! It's yucky though.
