Wow, 2 months of no contact over something you said??? I'm sorry to say this, but your chances are not looking good at all. How long have you two known each other?
I'm afraid to say it, but unless it was something really mild that you said to her that upset her (That you can pass off as some lame joke), then you should probably let this one go. 2 months is a long time (more than enough time to find somebody else).
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
