Why does nobody see what he did to his girlfriend? All career steps that she has achieved so far (her PhD, her publications, the research awards under the influence of the university or the ominous foundation,..) are basically worthless. Everyone discounts them and attributes them to the relationship with him.
Perhaps she is a decent researcher who could have achieved at least some of these things on her own. Does not matter. He took away the opportunity for her to get credit for it.
And what if she really should get a job in Innsbruck? There she is forever the girl who holds the position because she has been the professor's lover since college days. She never gets rid of that reputation and generations of colleagues and students will talk about her behind her back. Sounds like a nightmare.
There is a reason why such relationships are frowned upon and why there must always be an immediate separation of professional and private interests. In the end, the weaker partner loses out. (Among many other reasons.)
What now? If I were her, I would do anything to make a name for myself. Far away from Innsbruck, with projects, funding and publications that have nothing to do with him. And then maybe someday he will be the spousal hire.
