Bonny, you're spot on, I am definitely an over analyser.
I had thought of a dinner here and an invitation to all and then he can make the choice.
As with you, friendly and affirming works for me too but there's always the pull back. A friend of mine who is a counsellor (and who I don't usually discuss this with) said that H would be very aware that he chose to leave and get involved with someone else and to save face he would need to remain in the new relationship for sometime otherwise it's saying to others that he stuffed up again. Makes sense doesn't it? With H it appears to me that he doesn't want me but doesn't not want me either. It could change day to day!
