Divorce is always very difficult, ferlew. I hope your son is happier now
I think in time the law will change to bring same sex relationships in to adultery. It has to now that same sex marriages are legal - the grounds for divorce must be equal across the board. It would be a strange thing if a married lesbian couldn't divorce her wife on grounds of adultery because she'd had an affair with a woman yet she can if her wife has an affair with a man. An interesting point of law, so thank you for raising it.
