Pisces went cold after being hot

Long story short, it seems like she was sending me a lot of messages before going quiet ? I (Leo) am not that good at responding back maybe takes me a couple days or so.. lol or even longer. But I always enjoyed stuff she would text me about. Then she just suddenly stopped and idk what happened. Now she is acting kind of different and not as responsive.. should I keep trying to msg her? I still really like her and it’s just that since it’s long distance I don’t want to get all my feelings in it :/
