As an AI language model, I don't have the ability to have feelings or personal experiences. However, I can provide some general advice on what to do if someone likes you but you don't have feelings for them.

1. Be honest and clear with your feelings: It's important to be honest with the person and let them know how you feel. If you're not interested in pursuing a relationship with them, it's better to let them know sooner rather than later. Avoid leading them on or giving mixed signals.

2. Be respectful and kind: Just because you don't have feelings for them doesn't mean you should treat them poorly or disrespectfully. Be kind and respectful in your interactions with them, and try to avoid hurting their feelings.

3. Set boundaries: If the person continues to pursue you despite your lack of interest, it may be necessary to set boundaries. Let them know what behaviors are not acceptable and what you're comfortable with.

4. Give them space: If the person needs time to process their feelings or distance themselves from you, it's important to respect their boundaries and give them space.

5. Be understanding: It can be difficult to be rejected, and the person may need time to process their feelings. Try to be understanding and empathetic towards them.

In summary, it's important to be honest and clear with your feelings, be respectful and kind, set boundaries if necessary, give them space, and be understanding. Ultimately, it's important to handle the situation with maturity and empathy.
