In any dating situation, there will be times you say "oops". Women especially can get exponentially more angry than you expected. It normally means there is some unresolved issue that rears up subconsciously so you ask "where is this coming from?".
Here were the keys.
1) When she stood me up. My thoughts were:
1a) Did she block me forever?
1b) Is this over forever?
1c) How could she do this?
1d) Was ImTheDoubleGreatest right that a-hole?
1e) Can I phone her and microwave my brain while leaving voice mail?
1f) Can I show up at Taco Tuesday?
1g) Can I show up at her work and tip more than the landscapers?
1h) Is that waitress single?
1i) Is that bartender single?
1g) Is that other girl single?
I did nothing but text "Ok" and email "Did you just end our relationship?"
2) When she replied (in her normal poetic response which is why I love her) I did not reply. I just collected phone numbers, did push-ups, and listened to Iron Maiden and Judas Priest over and over. For 100 hours. I still have
Still Life,
Heading out the Highway and (a pioneering power ballad before its time)
Before the Dawn stuck in my head.
3) After 2-3 days you will suddenly see their side (beware being that apologetic, enabling dipsh!t, but chances are you weren't 100% right.
4) Know that some underlying issue was causing the majority of what happened, not the fact you might have made that comment about gays not knowing her uncle was gay (love you, Bobby Rio!)
5) WAIT - pissing off women is like accidentally stepping on a cat's tail - they will run off and if you chase them immediately they will only hide and try to bite you. But if you wait they come back at some random time.
6) When she responds, being the all-knowing Guru who figured it all out by then, reward her with a fast and warm response.
