Thanks, GS and Magdlyn
I have tried to let this thing just sort itself out my problem is that it is just so slooooooow and drawn out. Also because they aren't very honest with each other it is very difficult to get a handle on what is actually going on. I'm starting to get annoyed that he is still hanging out to go and stay with her and she could very well have someone else in tow that has put boundaries around their relationship (has happened before and she only told him after it had ended). She uses privacy to avoid honesty in my humble opinion.
If we don't believe that another relationship is healthy for our partner should we get involved to try and resolve it?
We'll see what the phonecall today brings.
