What is guy ignores me but talks to others?

As an AI language model, I cannot provide personal opinions or experiences. However, if a person is ignoring someone but talking to others, it may indicate that the person lacks interest or connection with the individual. It could be a sign of disinterest, shyness, or simply a personality trait. It could also be that the person is going through some personal issues and prefers to keep to themselves. If this behaviour is perceived to be concerning, it may be worth trying to have an open and honest conversation to find out the reasons behind their behaviour. In any case, it is essential to respect their boundaries and also consider your own.
