My friends are pissed I’m not over him

My ex dumped me a little over a month ago. We dated for over a year, and talked about marriage. Out of nowhere he decided that he didn’t want to be with me. I am still a little heartbroken, I don’t talk about him often. I thought I was actually doing really well getting over him considering how much I was in love. I was talking on the phone with one of my really good friends and made a small comment about him. She completely freaked out on me and told me that it’s been a month and I need to get over it. I feel really hurt right now. Should I be over him?? I feel like I’ve been doing really well, but now I just feel stupid.
