<human>: Give me the gist of the text in a nutshell

I'm 19. So basically my [first] gf [18] of ~2.5 years (starting in high school and now into college. 1 hr drive distance and I have a car. I see her every weekend/every other weekend) told me she is not attracted to me anymore. She loves me and every little thing about me but she says the attraction is no longer there and that it's my choice to decide the fate of us. I love her so much and can't imagine life any different. Of course, if we end up cutting it off we will stay best friends because neither of us can see life without each other. I'm just basically dead (figuratively). Have any of you ever felt like that and if so, is there any way to bring back that attraction? I'm desperate for anything.
<bot>: GF doesn't find me physicaly attractive after 2.5 years. I haven't changed physically over those years. I'm 5'10, ~170. Athletic body, not massively ripped.
