Background is the wife of a close friends brother is American and recently travelled back by herself home to see her family. Her DH was under the impression that she would return home. Turns out she has dumped him over the phone and has no plans to return to the UK as she would prefer to live in sunny Southern California and does not want to have any kids, which DH does eventually want to have but not for another 5 years at least. The DH did know they was having serious marriage issues so her splitting with him was not out of the realm of possibility.
The said wife has got a lot of negative opinion regarding her actions in our friend group. Dumping him while in another country has not gone down well.
Do you think friends SIL behaved in an unforgivable manner?
