Should I ask a girl (friend) why she is silent and distant?

It is not the first time she has done this. Its getting annoying like I don't know if I did something wrong to hurt her or is there is something wrong with her... thing is I try to ask her but it falls on def ears like she does not answer or ignoring me. I have a sense of self worth and am asking... should I confront her about her silence? Or should I just be the patient, passionate, accepting every excuse she throws at me? Like give her 2 months and say "Hi" and act like everything is fine?
