People's behavior can be influenced by a variety of factors, including their own insecurities, jealousies, or envies. However, it's important to note that human behavior is complex and can't always be predicted or generalized. That being said, certain kinds of people might be more likely to let someone down out of envy:
Competitive Individuals: Some people see life as a competition, and they may not want to help you if they perceive that it will give you an advantage over them. These people are often driven by a strong desire to be the best or to win at all costs.
Insecure Individuals: People with low self-esteem or who are insecure may feel threatened by your success or potential success. They might withdraw their support because they fear that your success will highlight their own perceived inadequacies.
Narcissistic Individuals: People with narcissistic tendencies often lack empathy and are primarily focused on their own needs and desires. They may not help you if they feel that doing so does not benefit them, or if they feel envious of your success.
Fair-weather Friends: These are individuals who are only there for you during the good times, but vanish when things get tough. If they are envious of your success or potential, they might abandon you when you need them the most.
Self-centered Individuals: Some people are predominantly focused on their own needs and wants. If they feel that helping you would compromise their own status or resources, they may refuse to provide the support you need.
Remember, it's always essential to communicate openly and honestly with people in your life if you're feeling unsupported. There may be misunderstandings or other factors at play. However, if you consistently find that someone is not there for you when you need them, it may be a sign that the relationship is not mutually beneficial and may need to be reassessed.
