My girlfriend is a flight attendant, flying around all the year round. What if you feel insecure?

First, think about what makes you feel this way. Because of her career? I feel that there is a psychological gap between you two.

Because she is a stewardess, maybe in this profession, she can meet people who are better and more motivated than you, so you feel inferior.

Secondly, her work flies around all the year round, which is also a long-distance relationship. Because she can't meet often, she is not sure about all kinds of people she meets, which leads to your anxiety.

The solution is that either she changes her job or you change your mind. Obviously, it is irrational to want her to change jobs, so you need to constantly improve yourself, make your ability reach a new height, find a balance in this relationship, and have confidence.
