It can be difficult to stop having feelings for someone you cannot have. The first step is to accept that the relationship will not happen and move on. Acknowledge your emotions, but don’t dwell on them. Find ways to distract yourself from thinking about this person, such as spending time with friends or engaging in activities that make you feel good. Finally, focus on self-care and building a life that makes you happy without relying on another person for fulfillment. With time and effort, you can learn to move on.
