I didnt love my baby (please no judgment)

So i got pregnant in December of 2018 unexpectedly. We were using protection and the condom had broken when we were having sex and I didnt think it was important to get Plan B because I thought i was about to get my period. I started having cramping and really thought my period was starting but I took a test after I was 5 days late and i was pregnant. The dad wanted nothing to do with me when i told him and wanted me to have an abortion. I had just turned 21. When i was pregnant i really didnt feel any attachment or love to the fetus/baby. I was extremely sad, shocked and scared. I know most people when they get pregnant say it was the happiest moment of their lives and they were so excited. It couldnt have been more of the opposite for me. People would ask if i was excited and i would literally answer them, "for what?" I felt like my life was over. I ended up having an abortion because i felt like i would never love my baby among other factors like not being able to support it and the dad not being around. Is this normal ? Will i always feel like this even when i have kids in the future? I never expected to have that reaction at all.
