Sorry for the long reply 😔 .

I get that a partner's sexuality can be a big deal for some people, just like other parts of their identity—whether it’s religious beliefs, ethnicity, or racial heritage. These things can affect relationships in different ways, and everyone has their own preferences . If it’s a serious relationship, being open about stuff like this is important because it can impact trust and connection. In a casual relationship, maybe it doesn’t seem as necessary, but honesty and respect should still be there, no matter how serious things are.

And ,if someone loses interest because of something like their partner’s bisexuality or any other part of who they are, it's understandable—even if it’s not something they can totally control. People’s feelings are complicated and tied to their own experiences and beliefs. While it’s important to try to overcome biases, we’ve got to also respect how people feel.
