So for some backstory, wife and I have been married for 4 years, and have one child who is under 2. We live on the east coast and our families live on the west coast. Generally we go back twice a year to see each side of the family and maybe once a year, our families come out this way.
My wife has always been very close to her family and me and my family are close but not call each other every day close, like they are. Over our relationship, there’s been multiple times of my wife planning things with her family for us to do and just never telling me. Generally it’s never been a problem except for one time years ago before kids. Caused a small rift but nothing that couldn’t be worked out.
This brings us to present day, I just realized my wife has been planning flying back to see her family next month with our child. Not a big deal right? Well I didn’t find out from my wife, I found out from my parents who brought it up on the phone. I said I had no idea what they were talking about, that it was the first time I was hearing about it. My wife had obviously told them about it at some point. Come to find out, this plan has been in place for atleast a month, tickets are booked and all paid for by her parents. I don’t even know what days.
Am I genuine in my frustration that I wasn’t even told about this trip or the fact that my child would be going along with? My wife still hasn’t even said a word to me about it directly, she spoke on the phone with her parents yesterday where they went over all the details. And to be honest, I’m a little mad I wasn’t even invited but this isn’t the first time I wasn’t invited to things with her family so I guess I should be used to it…
And to add the cherry on top, two months after they get back, my wife is planning another trip back with my child. Without me of course.
Anyone have any advice on this? I haven’t spoken a word of my frustration to her about it yet, mainly because I want to make sure I’m not overreacting. Any advice or things to say would help out a ton! I am the opposite of my wife and anything I plan, I do knowing my wife and child will be with me. If they aren’t with me, I generally won’t go. Its never even crossed my mind to plan something for me and my child to do without my wife being included. Let alone not tell her about it.
What should I do for that weekend while they’re gone? Go on vacation myself?

TLDR: wife planned two trips with my child to see her family and has yet to even tell me about it.
