My H keeps all his family and his one or two pre MLC friends at arms length. He was never one for going out much before MLC, and we would spend any free time together. He has never spoken to any of them about our situation, he kindly left that for me to do.
He now has a new group of friends, OW is a part of this group. I believe most of them are college tutors and OW introduced H to them. They apparently share a lot of interests, running, walking, good conversation etc. None of them know me so who knows what picture he has painted of me.
I don't imagine any of them know the 'real' H though, as he has only socialised with them all since his MLC.
