I would say go on with your daily life. If she wants to talk- talk. Give it time. I see in alot of girls that they just kinda "yea, whatever- don't talk to me" but, then talk. Sometimes it takes a couple of MONTHS even YEARS! Give it time. Try and call to her, sometimes people will have a Mediator or a Meditation (no not Yoga or ome of those) but you are in a Neutral setting, you sit at one end of the table, and she sits at one end of the table and you have a Mediator or a Mediator. They will help you work it out- each person gets to speak if they wish. Ours in town is called New Hope.
Everything old has past; behold the new!
You might even want to take a walk to your local physiologist or psychiatrist.
But 1st give it time.
Males are different they usual just talk about it and forget it. (that is what I think...but its Human, its natural.)
Again if you need a Mediator or Mediator go do it! Hurts NOTHING!
(I have studied them in school and role played! It really does work)
Asses the situation. Pros and Cons, what happened? Who? When? Where? Why? Think of all those.
Hope this helps and you can work it out. Give it time.
