Scared

I am a girl and have been with my girlfriend for 5 years. We are now struggling more than ever. I dont want to end the relationship, I am so scared. I am in love but as we both agreed, we are attached at the hip and have no personal time apart. I am trying really hard to focus on myself and give her space. We agreed to not plan on every days she has off as a day we have to be by each other the entire day. We do live together also.... so she asked for us to be together yesterday... but it felt so cold... I feel like she has removed herself. It doesn't feel right but she keeps saying things that confuse me. We are supposed to move from Florida back to her hometown in Ohio in about 8 months.... but I am scared. At this point, this relationship is not moving back for. I dont want to lose her but I feel like the attempt to fix things is one sided. I dont know if I should hang in there and just give it more time with giving her her space or if I should start to let go, knowing that it may end. So lost. I want nothing more than to have her love back and be with her forever.... but she is not reciprocating any of those feelings.... so scared and lost...
