How do I deal with a moody girl friend over a long distance relationship?

So, I've been with this amazing girl for almost three months now. Some days are great, we get along, we talk on the phone, we text, everything. And then others, she barely talks to me, doesn't call, and then when asked why cops an attitude and wants to break up. Granted, she never means what she says when she hurts my feelings, and always makes it up to me, but how do I avoid these terrible days with her, I want our relationship to be normal ALL the time, not just once a week.How do I deal with a moody girl friend over a long distance relationship?
long distance relationships are hard. If you two have meet in person, it might come easier. them you would have more to talk about. If you have never meet, then it sounds hard. find stuff you both like to talk about. distance is stressful. hope you find happiness.
