My girlfriend says she wants to move out.

My girlfriend says she loves me and wants to stay in a relationship with me, but she wants to move out on her own. Pardon my French here but this sounds like bullsh*t. I fought with her since March over this now she's say her therapist is saying its a good idea for her to move on her own...and by her therapist I mean she says her therapist said. I fought to keep her with me but now I feel like screw it why should I be the on,y one fighting for the relationship. She cries when I said she didn't love means didn't care. But I truly feel like she doesn't love me anymore. I just don't know what to do. I do love her but I'm tired of feeling the way I do, tired of feeling like I'm the only one who cares. Should I just let her go and see what happens?, because to me her moving out alone is the death throws of the relationship.
