The more you pretend about how you feel about someone, the more difficult it becomes for you to stop yourself from liking someone.
Talking to someone can always create a sense of connection, likeness, or affection, especially when you like the person and want to be with the person.
You may have to create strict rules and regulations to set boundaries between you. Some rules may include no visitation, no dates, no discussion of intimate subject matters, etc.
If you want to stop liking someone, you should stop being with or around them. Find someone else to help you with what they used to help you with.
It would be best if you focused more on your studies in school or paid more attention to your job or business at the office, as the case may be. Take up more assignments and ensure to complete them.
If you do not have school or work activities to get you busy, find something to do to ensure you are not idle.
Make sure you have fun to the point where you only remember when you’re alone and how much fun you had with your friends at the beach, cinema, restaurant, club, etc.
If being in the same neighborhood makes it difficult for you to stop seeing and liking them, then it would be better for you to migrate into another apartment far from where you can easily reach them.
During a date with someone you know is interested in you, you may find out this person has better qualities than the other.
