bf doesn’t like my natural voice?

i’ve been with my bf 3 years and we are 17 i’ve been faking my voice the entire time because i have a naturally deep voice that got made fun of all my life so i started using a higher softer tone. i realized i can’t just hide my natural voice from him as long as we’re together, i don’t talk like that in front of family so eventually things would just get embarrassing yk? so i used my natural voice in front of him for the first time in 3 years and it was really hard. he instantly was turned off. he looked at me weird and asked why my voice sounded like that and why it was so deep. i instantly shut up and he kept asking all night why i sounded like that. i was embarrassed and just acted like i didn’t know what he was talking about. well a couple nights ago i told him how i got bullied for it and people ask me if i’m trans often and overall i’m insecure of my voice and thats why i hid it and i told him i felt like he was turned off by it and his response was “oh. i like it” it just didn’t seem genuine and the way he acted says otherwise.
