What if my popular boyfriend finds someone better?

I just started dateing a new guy and he is really cute and funny, next year he starts highschool , and I am so scared he is going to find someone better. 89% of the guys I have dated have moved on to a better girl but they werent as attractive as him so I am jsut wondering if theres a way I can tell him how I feel w/e him thinking I am the jealous type or like obbsessive or something?

Do I sense insecurities and low self esteem. You have to have confidence in yourself. You know you have good qualities and thats what led him to be attracted and having a relationship with you. If he moves on to another female than that should let you know what kind of guy he is and what you meant to him

Honestly, why would you even want to be with a guy who you think would move on to another girl once he gets bored. I mean you are only assuming this right now and this does not mean that he acctually would do this. I am not saying that you should break up with him because you think this but at the same time you should prepare yourself for this possibility. Do not get too attached to him if you do not trust him. Do not do whatever he wants you just so that he will stay with you either. If he does move on however, then he was clearly not worth keeping. It's an experience that will help you make better decisions in the future.
