Being told not to come to son's wedding

We did try, we left a message on their phone asking them to please call us and that we do care but have heard nothing. I feel anxious to try again, in case it makes it even worse.

Surely there's more to this than being uninvited ? What caused the argument with his fiancé and why was he blaming you for getting married in the UK?

I know weddings can be fraught but this seems to be the culmination of several incidents doesn't it?

I'd tread very, very carefully, it does seem an extreme reaction.

So many grown up children seem to want to have their wedding abroad and cut out family, I really don't undrestand it.Family and friends around you on your wedding day is what makes it wonderful.
sorry you have this problem, try and talk to them as soon as possible, say things got off on the wrong foot ( as these things often do) and let's try and make things better.Good luck.
