Well not ex cathedra means not a dogma that can't change - so that is what.  And its a what that matters a lot.  

Where is your proof that God did not call me to priesthood?  This accusation which you cannot prove is sinful and hurtful and you are responsible to God if you do not repent of it.  Not being ordained because our bishops, for now, still support sexism in this church is not evidence.  Evidence would be some kind of writ which you could prove was written in Christ's own handwriting stating that Nora Bolcon was not called to ordained priesthood.  If simply not being ordained yet meant a person was not called by God, then none of our seminarians are called by God to be priests because they are not ordained yet either.  
Trent was a council which the emperor demanded women be kept out of having a voice.  This created a biased council to start with, and since God does not respect sexism, even though Constantine did, this means we were wrong to allow the bias then.
