When a guy talks to other girls but consistently ignores you, it can indicate a few possible reasons. However, keep in mind that I don't have specific knowledge of your situation, so these are general possibilities:
Lack of Interest: One possibility is that he is not interested in you romantically or doesn't see you as a potential partner. This could be why he engages with other girls but seems disinterested or distant when interacting with you.
Shyness or Nervousness: Some guys may act aloof or ignore someone they are attracted to because they are shy or nervous around that person. It could be their way of trying to avoid showing their feelings or vulnerability.
Mixed Signals: It's possible that he's sending mixed signals, and his behavior might be confusing. He might like you but is unsure how to express it, leading to inconsistent behavior.
Prior Commitments: He might have other obligations or commitments that are taking up his time and attention, causing him to be less available to you.
Relationship Status: It's essential to consider whether he is already in a relationship or dating someone else, which could be a reason for his inconsistent behavior.
Personality Differences: People have different communication styles and ways of expressing interest. Some guys might be more outgoing and social with everyone, while others might be more reserved and selective in their interactions.
Regardless of the reasons behind his behavior, it's important to remember that you deserve someone who respects and values you. If his actions make you feel ignored or undervalued, it might be a sign that this person is not the right match for you. Open communication is essential in any relationship, so if you feel comfortable, consider discussing your feelings with him to gain clarity on where you stand. If he continues to ignore you or shows disinterest, it may be best to focus your attention on someone who appreciates and reciprocates your feelings.
