He pushed her in to a corner and kissed her. She kicked him out.
His behavior is totally inexcusable. No question.
But seriously? Do I live in an alternate reality where drunk people do all sorts of borderline illegal inappropriate stuff on a regular basis?
Because in my world people do that. And it sucks. And no one likes it. And it can and should be called out. But I can't imagine it haunting anyone for years, especially not someone who has the strength of will to start a company.
It may seem insensitive, but I am being pragmatic: whether or not something "haunts" you has as much to do with your way of framing an event and your attitude towards trauma as the actual event.
Just because someone else did something wrong is no reason to carry it with you for years.
This is no commentary on whether or not this guy's pattern of behavior is reprehensible. I am literally talking about that one incident in isolation and its effect on the author's psyche.
