no romantic attraction

i feel like i'm a terrible person, i'm dating this girl, i have been for a couple months, but i don't feel anything towards her- she's a wonderful person, and i like hanging out with her, but i just can't feel anything towards her. i thought maybe that my respect and admiration was affection but it just isn't, and she's- idk if it's love but she's very into me- romantically. idk what to do she's my best friend, the only person in my life that i feel like i can be honest with, except about this... ive known for a while that im aroace but i thought maybe im demiromantic and all my feelings for her were romantic, and i feel like i'm lying to her and she doesn't deserve thayi feel like i'm a terrible person, i'm dating this girl, i have been for a couple months, but i don't feel anything towards her- she's a wonderful person, and i like hanging out with her, but i just can't feel anything towards her. i thought maybe that my respect and admiration was affection but it just isn't, and she's- idk if it's love but she's very into me- romantically. idk what to do she's my best friend, the only person in my life that i feel like i can be honest with, except about this... ive known for a while that im aroace but i thought maybe im demiromantic and all my feelings for her were romantic, and i feel like i'm lying to her and she doesn't deserve thay
