dragon girl and rabbit girl, friendship failure?

I'm the dragon she's the rabbit. We have been best friends since Middle School. But our friendship is always on and off. When we have fun we have real fun. When we laugh we really really laugh so hard that we need to pee. lol Our friendship is really strong. Yet, now we don't talk anymore because our communication is so poor. Like i truly feel we are both karmic to each other. It's just always on and off. But this time I just don't want the friendship anymore. I just feel so tired with her. Is this why Rabbit and Dragon are incompatible?? Whats really the reason why?
