I'm bi but I like someone who is straight?

It's common to develop feelings for someone who identifies as straight, even if you're bisexual. It's important to remember that attraction doesn't always lead to mutual feelings or relationships. Consider focusing on building a friendship and see if there's any openness from the other person, but also be prepared for the possibility that they may not reciprocate your feelings. Ultimately, prioritize your emotional well-being and explore connections with those who are interested in you as well.
