As the title says, [19m] and [16f] dating for 9 months.

 For the most part thing are good. I don't really have any complaints about her, and I don't feel that anything is wrong on a personal level. My only issue, I suppose, is that I'm kind of getting bored. Everyone I've talked has told me it has a lot to do with my age, but is that the case? I do certainly feel like a lot of my personality and ideals are changing recently.

 My other issue is that, if I did decide to end it, she is VERY attached. I DO care about her quite a bit, she's a great, sweet girl, I'm just not sure the relationship is necessarily right for me. Having typed this out, "bored" almost seems like a dirty word to me. It's not that I don't enjoy the things we do together, I just don't know that this relationship is going to go anywhere. Do I wait it out and stay? If I do leave am I an asshole?
