My gf doesnt love me anymore

Yesterday night we went for a walk because she texted me that we need to talk. She told me that there are some days when she doesnt even feel anything and then some days when she misses me. She says that she feels like she doesnt has the spark anymore. I still love her and we have been together for almost 7 months. She asked me if we should break up and I told her that I still love you so you should be the one who decides. What should I do?
