A boy keeps saying that I have changed recently, that I talk to him differently, that I am not the same person as before, that I have become skinny, but I don’t feel that I have changed.

If you feel that you have changed, you should actually think about his subtext.

1. If he says you have changed, there must be a certain reason. A person would not say something incomprehensible without a reason.

2. Think about why he said such things to you. Have you behaved differently recently? Or maybe your attitude towards him is different.

3. You can try asking him why he said you have changed. What has changed? This way you can find out what he is thinking. You can know the reason.
