Roist, Thank you for your reply. This has really been bothering me. I see this group of people nearly every single weekend from spring to fall as we all belong to a camping club together and go camping every weekend. As this is something H and I have always done together, him not being there is very noticeable, and I have 10 adults and 7 kids asking where he is constantly. There are only so many excuses that make sense and I am running out of them.
As one of his issues is avoidance of anything remotely uncomfortable, I had also sort of decided not to be the one to tell them myself because I feel if he wants to leave me then he should own up to it and tell them himself. But, once again...as he his avoiding them, our closest friends, I am the one who is getting all the questions and confusion about why he has done a disappearing act.
