Do you think Louis will ask Rome for an annulment?
I’m not sure what grounds he would have ? It is not as though he got pushed into marriage... it was after the first child was born and they had been living together. And mentally incompetent is a stretch as he went on to get degrees and apparently works in a professional capacity. And Tessy not being prepared to have a child within the marriage or not consummating the marriage is clearly not the case. And the last option would be one or both at the time of the marriage was not committed to it for the long term which would be hard to prove.
The Lux family apparently tried to head off a separation.... so it would be difficult to now suggest Tessy was somehow an inappropriate partner.
And I doubt they would try on the basis of the behaviour of Louis... would hardly show him in a good light to his future wife and her family that employs him and their clients. So Tessy would be the only one who could do that and she hasn’t shown interest so far.
So I don’t see a Catholic marriage
