Help!

I got into an argument with my husband this weekend about how I never feel that I am included and informed about things happening in our lives. I usually find out after the fact: financial decisions like buying property and not informing me until it's happening, plans he makes with his family etc. After the fact: we get into another argument because he randomly tells me that he planned for his family to come visit us for 2-3 weeks in the summer. He hasn't booked anything yet but told me that they are coming. I told him June wasn't a good time and they could come later in the year. His response was: it's my family I can do whatever I want. Also my in laws don’t make the situation better they will make decisions for us.

Am I overreacting? How does one handle a situation like this. This is the 2nd time this is happening where he plans to bring them here without talking to me first.
