I know I have extrapolated a great deal from the little information provided

Yes you did, Naemanson, and you may well be right in your extrapolations. But you might equally be wrong, because it would be possible to extrapolate lots of different stories from the hints we've been give. Inevitably we are all liable to read this as being similar to some story in which we have had some involvement. But it's dangerous giving advice without knowing a great deal more than we have been given.

It's a human instinct to try to advise when asked for advice. (Assuming we have been, which is open to question. But I think it is a good rule not to risk erring on the side of being unhelpful, just because we might be taken in. Chesterton once said something on the lines "The man who is always taken-in sees the inside of everything.) But the only real advice that can be given here is to tell the full story to someone who can be trusted.

Whether that's going to mean counselling or advice is another matter. Counselling in this sort of context doesn't mean giving advice, it means helping someone decide what it is they really want. Sometimes what people really want actually is advice.

Here's another Chesterton quote, from something I was reading only yesterday:

If people can be divorced for "incompatibility of temper", I cannot conceive why they should not all be divorced. I have known many happy marriages, but never a compatible one. The whole aim of marriage is to fight through and survive the instant when incompatibility becomes unquestionable. For a man and a woman, as such, are incompatible.
