Help?!? Idk if i actually like my bf

Ok so my bf and I have been dating for almost a year. We are each others first real serious relationship and he is honestly amazing. like I truly believe he is the person ive been manifesting/praying for my whole life. logically i know how great he is so when he says I love you I say it back, however I dont feel anything. He never gives me butterflies or makes my heart race. I dont have any experience with being or feeling loved so maybe Im looking for a feeling that doesn’t exist but I know how much he cares for me and i feel like i give off nothing back. Due to life, I do think i have emotional detachment issues but Ive had crushes before that made me dizzy. This problem has been eating at me so badly i cant sleep. I thought in the beginning that the feelings would just grow stronger but its been almost a year. He doesn’t deserve someone who cant love him properly? Should I break up with him? Someone please tell me whats wrong with me😭
