My brother died at 23, 5 months ago. I’m 19 and have no other siblings. I’m in college but living at home right now because I just felt like it was the right thing to do. My mom is just a mess since it happened. Our family is barely functioning right now.

Around Christmas, his ex-girlfriend reached out and said she’s pregnant and that the baby is his. She’s very pregnant, like due on March 2.

They were broken up when he died. She had moved out. My brother told me he was done and trying to move on. As far as I know, they hadn’t seen each other in weeks. He never mentioned a pregnancy, a scare, or that they were still involved.

She waited until months after he was gone and then contacted us saying she wants to “keep his memory alive.”

My parents immediately went all in. They offered to move her into our house, pay all pregnancy and baby expenses, buy her a car, and support her long-term. No questions asked.

I told them that grief doesn’t replace basic due diligence, especially when they’re about to make irreversible financial and emotional commitments. I’m a guy and its not like I know much about pregnancy but I researched prenatal paternity testing and found out it can be done safely through a blood test before birth.

Now I’m being treated like I’m heartless by everyone involved.

She says I’m accusing her of lying and stressing her during pregnancy. My parents say I’m being cruel, that they’d rather be wrong than turn away a possible grandchild, and that “this is what my brother would have wanted.” I said we don’t actually know what he would’ve wanted. What’s the big deal about asking for a paternity test? If it’s his baby like she claims, it shouldn’t be a big deal, right?

That comment blew things up. I’ve been told I’m heartless, and trying “punish” a pregnant woman. She keeps making remarks that I’m jealous and that I should stay out of it. It just seems so weird that she’s talk to me that way when she never treated me like that when he was alive and they were together. Jealous of what? A baby? I’m almost 20 years old. The whole way she showed up and told us the news was just so strange, I can’t explain it. But no one can explain why asking for proof is unreasonable. My mom has basically barely functioned since he died. She lost her job. I’m worried that if there’s any chance this isn’t real, it’ll destroy whatever she has left inside her.

AITAH for calling this reckless and insisting on a paternity test before my parents financially and emotionally commit?
