I can't connect with my baby..

Please no hate. I am really really depressed and confused about my feelings. I have been dating my current boyfriend for over a year and have known him for a long time. We started dating shortly after I got out of a pretty serious relationship. I was confused about my feelings and where my heart was but my now boyfriend has medical problems and I feel if I leave him he will go down hill. I am pregnant with my first child, he wanted a baby really bad and he loves me so much but I am not in love with him I love and care for him but just not the same as he does me. I can't feel happy about this pregnancy or feel like maybe I jumped into it a bit too soon. I sometimes resent my unborn baby, I have been crying for days, thinking of what to do or if these feelings will go away. I don't know what to do or how to feel anymore. I feel terrible because all babies are precious and i wish i could love this baby but i just cant. What should i do? Has anyone else felt this? Is it just hormones ? 😭💔
