How do i know i still wanna be with my girlfriend?

My gf and I have been together for almost a year and she's on a tour across the US for hula. She come back on June 29th but she was not aloud to bring her phone so I have to wait till she come back. I'm forgetting how being in love left from her being gone for so long. I truly love her and she truly loves me, I just don't know what to do.
