My coming out experience

Hi everyone
So I came out as bissexual to my parents last year, and my mon just sort kind of asked me if I liked girls and even though I didn’t plan on telling her that soon I didn’t want to lie.
Fast forward a couple of months later and it’s like they don’t acknowledge my bisexuality, my mom has a hard time seeing this part of me because in her head I’m straight and anything other than that it’s ugly or sad. I think she just doesn’t want to deal with it honestly. I don’t try to hide it but it’s difficult to look at her the same.
And I don’t know what to do in this situation because it’s not like I can make her try to understand, so I just pretend that I am not hurting when everything she says makes me feel like she doesn’t love me whole.
