I need advice...

So I'm a 13 year old and I'm bisexual, I came out to all of my friends this year loud and proud, but alot of my friends said the same thing

they said that they would be fine with me being lesbian or straight but being bisexual is disgusting.

I really like hanging out with these people and besides them saying this they have been really good friends, I don't know weather to stop being friends with them bc they don't accept me or stay friends with them, but the other thing is, that they bring my bisexuality up alot and in a bad way, idk what to do, someone help me
