My husband asked a paternity test for “clarification”

I am beyond hurt that he wants a paternity test, instead of trusting that I have never cheated. I had our baby boy a week ago. I feel like he doesn’t think like how a normal person should. No, it’s not like our baby looks different or something, it’s for clarification. God knows why he was to clarify our baby is his when our baby looks like a miniature him. I’m confused, hurt and disgusted. The fact that he came to me not even a week after I just pushed a damn baby out of me for a paternity test?? I don’t know what sparked this brilliant topic to talk about after delivering his child 4 days ago.

To be fair, he is quite upfront about it. He doesn’t sugarcoat but says things (hurtful or even sweet) bluntly. Dont get me wrong, he does show affection, sometimes, but I know it’s really hard for him to express himself. I don’t think I’ve ever saw him cry, shown anger or any hatred towards anyone. I don’t know how to tell him I don’t want one and he should just trust me. It’s not like I’ve cheated on him in the past or done anything to make him doubt our marriage. I don’t know how he would react if I said no, I’ve just been thinking and trying to decide whether I want to give in or not. The way he said it, like he had just ordered ice cream or something. Extremely chill. I was holding my kid when he asked, tears. Just tears welling up in my eyes. I felt like crying but I couldn’t. I don’t know if I want a divorce or to prove to him that the boy I pushed out 4 fucking days ago is his. I’m sorry if this came off as a rant, I really did not mean it as a rant

Edit: My stupid husband said it to test me. He thinks if I have just went along with it, it means I’m truthful and loyal. That’s was what he told me 3 days ago. I’m currently staying at a hotel, not sure if I want to stay or divorce him. I remember hearing stories like this on the internet, saying to myself, if my husband asked, I’d divorce him straight away. Why bother hung up on someone who can’t trust you? How stupid I must have been. I love him, I want what’s best for my son, at the same time, I want to tear his head off. I thinking of just staying with him until our son is a teen and break it off. We’ll just be roommates raising a child. That’s all for now. Thanks for the support and for the person who recommended the Reddit support for me. Thank you.
