AITA For Getting Upset A Stranger Held My Baby.

Okay. My boyfriend (27m) and I (26f) have been together about two years now but on and off since high school. We’ve always felt like end game & end up together. But I love him and our baby (1m). This is my second baby. During our last off I was with my ex; who was so abusive to me that it gave me PTSD which my current bf knows a bit about. So I’m protective over my kids. Always have been that way to be completely honest I’m more of a reserved person. He is so trustworthy.

So a last night we went to a chain restaurant for his cousin (22m) birthday let’s call him Cousin with most of his family so about 15 of us total. Now I need to give you context. Cousin has a girlfriend (21f) let’s call her GF. Never met her. Heard of her twice in the two years maybe. But Cousin moved her down here from a different country. Now before yall get defensive in the comments we’re the same ethnicity. Now Cousin goes to this country quite frequently. Don’t know if this is the same girlfriend from last year. My boyfriend can’t tell me cuz he doesn’t even know.

Get to the restaurant get out the car say hi to Cousin & GF stands there outside our car my boyfriend is with our baby in his car seat. No hi no intro nothing immediately she goes for my baby. I say nothing (I’m trying). My boyfriend had met her boyfriend once I believe since she’s moved down here. My boyfriend hands over my baby. I say nothing. He’s in a car seat that’s fine with me.

I get in the restaurant. She’s got my baby in her arms. Mom rage immediately activated. Any mom knows this. Why is a stranger I don’t know touching my baby. I’m already sketched out bout them carrying him in a car seat. We get in say hi to everyone my boyfriend knows I’m upset he can see it. I say nothing. His grandma can see it and tells me to sit with her. I’m quiet.

Couple minutes into the dinner I realize we don’t have my sons bottle. I go to the car to get it cuz I need air. I can’t find it. I ask my boyfriend to help me find it. He comes out. Still sees I’m upset asks a second time he keeps on asking as I tell him we can talk about it later. But he won’t drop it so I tell him why I’m upset. He proceeds to tell me how I’m overreacting and I’m the ONLY one with the problem. “You are the only one that has a problem with her” (I do start cry cuz im hormonal still it’s not funny.) I can hear those words over and over in my head. We can’t find the bottle. He goes inside leaving me outside alone teary eyed and upset. I call my mom to calm down. Ask if I’m overthinking it and she reaffirmed me I was not. I text him I’m going to the bathroom no response at this point in debating leaving with my son. But I can’t cause a scene so I mediate a bit and go back. Finish the dinner and he acts like all is fine. We never talk about it again. It’s the next morning but his words are engraved in my brain. He changed how I now look at him. He’s LITERALLY DEFENDING A STRANGER INSTEAD OF ME. No apology. Am I the A**hole or overthinking?
