P.S. Do some research on HPV, which is the most likely scenario (but certainly not the only one...her results may have nothing to do with sexual contact).
She could have had the virus for years and it's now cropping up because of age or stress. It could be a testing anomaly and resolve itself before the next test...I assume the next step is a repeat Pap or a colposcopy?
I have been through this, had a cone biopsy and had normal tests ever since.
The point is, none of this is a reason for you to resume drinking. None.
At some point, you may well need to address the past with her, preferably with some professional guidance. But right now is about her, yes? You getting drunk will only make things worse for her as well as for you.
