Rude!

I came to my in-laws with my husband to change his breaks with his dad. I’m inside talking to his mom and his brother. Well it was taking way longer than expected because he had to get a different part. Anyways the whole time my MIL offered my BIL something to drink but she didn’t offer me anything. Then my BIL and I started talking and eating some peanuts she had on the table. Well she noticed and asked her son if he was hungry. He said he was okay but my MIL insisted and offered to make him something to eat and he finally said yes so she made him a sandwich. I thought it was rude that I never was offered anything even just being there made me uncomfortable as he ate. Then my husband came inside after he changed his break and she offered to make him something to eat! At this point I felt really upset but she never even offered me, only her sons. Mind you I’m 13 weeks pregnant and it just made me feel like she didn’t care about me because I wasn’t her blood. Am I overreacting?

Update: I told my husband when we got in the car, he was very upset with her and agreed that she is being passive aggressive. He said that if he was inside with us he would’ve asked his mom why she never offered me any. And to add I’m the “favorite” daughter in law, imagine if I was the least favorite 🙄
