Yep, it's all about jelousy and self-centredness I'm afraid. I think it would be good if you could have a frank discussion - like Snowy says, butter her up first so that you won't look bad when you move in for the kill! Also, I agree that it is so important to get your H on your side so that he can stick up for you if neccessary. It might take time to prepare but it would be worth it.

Personally, I would have lost interest in them long ago - I just have no patience with people like that whoever they are. However, that would leave you with the problem of an atmosphere every time you have to meet at weddings etc. so much better to try and sort it if you can bear it!

Best of luck Sussexgirl, let us know if you make any progress!
