AITAH for getting mad at my friend so being so judgmental about my love life?

Let me start by saying that I love all of my friends, and I completely understand that everyone is allowed to have their own opinions and views.

I recently started talking to a guy I knew a while ago. Things didn’t work out between us back then simply because the timing wasn’t right. We recently reconnected, and honestly he is everything I’ve ever wanted in someone. I’ve even told my friends that.

Yesterday, I was sitting down with one of my really close friends and telling her about him. She stopped me halfway through and said, “If you start dating him, I’m going to be really upset.”

Obviously, I asked her why. I wanted to hear her perspective and understand where she was coming from, but she couldn’t really give me an actual reason. Instead, she told me, “I just know he’s not your husband.” (Please note I’m 21 and not ready for marriage at all)

She then explained that she has a certain idea of the person she believes I’m going to marry and that I shouldn’t settle until I find that person. But to me, it almost feels like she believes she needs to approve of the person I date and that they have to fit her idea of “perfect” in order for me to be happy.

She has even told me that I shouldn’t start dating anyone until December, which I honestly find strange because I don’t understand how she gets to decide when I’m allowed to date.

I understand having concerns about a friend’s relationship. If someone is being mistreated, manipulated, or genuinely hurt, I absolutely think friends should speak up. But in this situation, she hasn’t met this guy, doesn’t really know him, and is making assumptions about who he is and whether he is right for me based solely on her own idea of what my future husband should be like.

I told her that it’s my life and that I’m allowed to get to know whoever I want. Just because he isn’t her type, or because she personally doesn’t see him as my future husband, doesn’t mean I shouldn’t be given the chance to see where things go.

I’m starting to realize that my friends’ opinions have a pretty big impact on me, which is why this has been getting to me so much. I don’t want my friends to blindly support every person I date, but I do want them to support me and trust that I’m capable of making my own decisions.
So, am I the asshole for telling her that she has no say in my love life and that I’m going to make my own decisions about who I date?
