The differences between emotional immaturity and maturity are almost 180 degree differences. The person who is focused internally, seeking self-satisfaction and gratification is immature while the adult who is more concerned with their partner than them self is mature. The person who doesn’t take responsibility for their actions is immature and the person who doesn’t use “It’s not my fault!” as an excuse for anything is probably not.
People who are immature are often emotionally volatile. This means that they are more prone to emotional outbursts in which you are left feeling deflated and hurt by their yelling and accusations. Their emotions get out of control and you are often the focus of their anger. Although we all experience the occasional outburst, they shouldn’t happen more than once or twice a year. For people who are emotionally immature that number can be as high as once or twice a week.
Within the category of emotional volatility you might be on the receiving end of these situations: temper tantrums, inability to take criticism, extremely jealous, unpredictable moods, unwilling to forgive and their response is completely out of proportion to the situation.
Individuals who are mature don’t exhibit these behaviors. They may get angry but they don’t usually get out of control or get angry out of proportion to the situation. Emotionally immature people may also be more dependent upon you than what you would normally expect. They would like someone around most of the time and aren’t satisfied with their own company. They can be very easily influenced by others and make decisions based on the opinions of others. They also appear to be very reliant on others to do things that you would normally think could be done by themselves.
Differentiating between people who are immature and someone who is just having a bad day or a bad week requires that you have a relationship that has lasted more than 1 week. It’s difficult to make this differentiation when you know someone a short time, so be careful about jumping to conclusions about someone when you first start dating.[:]
