hi ive been lurking here for awhile. ive been in a relationship with this girl for 3 years. shes 20 and im 19.

idk for as long as i can remember i was always asking myself whether i wanted to breakup or not? she didnt do anything wrong in fact she supports me and i support her and its all really swell and im pretty sure im in love but idk.it just doesnt always feel... right. idk i always feel like i shouldnt be with her and i should break up w her and try being in relationships with other people.

im not sure if its because i want to experience being with others (this is my first real relationship with someone) or if im just being stupid.

i know that love is a choice not a feeling and all that and half of me is scared of breaking it off because im sure ill never have anything as good as this (its a really good relationship), but part of me feels like ill just grow old feeling as if im empty inside if i just stay, and she really doesnt deserve that. maybe its just going too fast (were aiming for the the future already) or maybe im just too young.

any advice?
