RANT!

I don't even know what to feel right now. I'm angry, upset and confused. My husband, my mom and I were all sitting together. My mom gets a call from my sister. She tells her to come over because she had guests over. Family friends we have known since before we were born. They are 4 sisters, all within the same age group. We all basically had a shared childhood, every single moment was spent with there family. Once we all grew up 15+ years old school, college, marriage everything kinda made us go our own ways. Now we meet them twice a year. Back to my mom, she asks my husband if he can drop her off. Me, thinking that I was invited, because that's been the case for 15+ years all of a sudden goes "no, I'm wearing this n that n I don't wanna go." I noticed my husband and mom exchange a look. No one says anything, it's dead silent. Then my mom goes, "it's ok, just come." So I take my son and we go. As I enter my sisters house she gives me this strange look. Anyway we stay for an hour or 2. My husband came to pick me up. I tell him how our 1 year old was cranky right when we sat down. He did not sleep the entire day, and it was 10 pm then My mom goes, "go home, he's tired." Like very rudely. My husband was like, "you know you weren't invited." And I'm like, "well thanks for telling me now." We've been together for 10 years. Whenever he says or does something wrong I tell him. That's how our relationship was. We tell each other everything, and never once thought we were dating or married. He goes, "I didn't wanna embarrass you." My mother is very, very nasty towards me. I told him she doesn't care about my image, or anything. he could have texted me and been like, hey don't go, she didn't invite you. It didn't click in my head. I legit assumed I was invited, that's how it's always been. Now that I think about it she seemed angry the entire time.
