Emma,

I remember going through this in high school. To be honest, I think most young men are not very good at expressing themselves, or even at knowing what they really want from someone. They are not taught to reflect on such things as much as women are.

I think if you are interested in other guys, you should focus more on them and maybe develop friendships so that you feel there is more in your social life than just your boyfriend. Even if you aren't looking for a relationship with anyone else, it helps to connect with friends, because you will realize that lots of people are plenty interested in you and they may have as much, if not more, to offer than the guy who is making you feel this way.

Best of luck.
