The fact that someone frequently comes to your mind doesn't necessarily mean that you are always on their mind as well. Our thoughts are influenced by various factors, including emotions, memories, and experiences. It's natural for certain people or past experiences to occupy our minds from time to time, especially if they had a significant impact on us.
However, the frequency with which someone comes to your mind might not directly correlate with how often you are in their thoughts. People's thought patterns and the reasons they think about someone can vary significantly.
To understand whether you are in someone else's thoughts, you would need more direct communication or cues from that person. If they regularly reach out to you, mention you in conversations, or show signs of thinking about you, then it's more likely that you are on their mind as well. Nonetheless, keep in mind that people process thoughts and emotions differently, and it's not always easy to gauge someone else's inner world based solely on your own feelings and thoughts.
