Why wasn’t I invited?

My boyfriend and I have been dating for almost 3 years. We live together and support eachother.

I am family oriented. Whenever my family has an event, comes to visit, invites (us) to dinner; I constantly remind him or ask if he want to come and usually he doesn’t but my family and I still talk on the phone a lot in which he joins our conversations. My family loves him.

I’ve met his family a bunch. We drove to see them during Thanksgiving and stayed there for a week. His mom and I (I thought) really bonded and had a fun time. But when she came down to visit; I wasn’t invited to dinner, breakfast, or touring. I shrugged it off thinking maybe they just wanted alone time. When his grandma died, I wanted to go with him for support and he didn’t want me to come. Okay - maybe he wants to do this alone with his family. That’s fine.

I get home around 9pm last night and call him to see what he’s doing and he’s at dinner with his brother; who just came to town from OR. Okay, why wouldn’t you tell something important like that? Why wouldn’t you have invited me to dinner? We had a great conversation when he got home about how I felt like he didn’t want me to be a part of his life and that I would have like to be invited because I think of him as my forever partner and I don’t like feeling like I’m just some chick. He agreed and apologized.
NOW - guess where he is. Yeah, dinner with his brother that he barely tells me about as he is getting ready to leave the house. I was obviously upset and he says “well what do you want me to do - cancel?” And I’m like no, maybe you could have just invited me instead! And he says I’m totally overreacting and I feel just really hurt about it.
do you think I’m overreacting?
