At the beginning of DC starting primary school a mum from the class had an affair with another dad in the class. The married couple broke up and the couple got together and have been together ever since.
There is a lot of bitterness from the ex partner and everyone knows in the playground.
Fast forward 6 or so years the couple that got together following the affair have decided to get married and are planning a wedding. The bride to be is obviously excited and you can see the excitement and plans on FB with tags at venues etc.
My friend is close to the ex wife and she has shown text messages from the ex husband (I hope you're all following who is who - feel like a flow chart is needed!) that are at best flirty, at worst the beginning of something more. Ex wife has said she will take revenge when the time comes by sleeping with him and telling the other woman.
I feel bad every time I see how excited the bride to be is, I'm friends with her and the children are all going to be hurt when this happens, obviously IF it happens...
There isn't anything I can do though is there?
