Although she knew I was going to do it, and seemed supportive, this close friend still burst out crying when I said I was going ahead. I have suffered verbal and emotional abuse, but not physical. Stbx does not fit the picture of a charmer, but he seems like an ordinary bloke to everyone else. I have promised her I will tell him that for her, this will not affect their friendship, however I am not so sure stbx thinks he is friends with her, tbh.
She's fine now, and tends to process things by being a bit emotional, and then getting over it, it's just her way, but it just seemed to highlight how difficult, nay impossible, it is to tell people anything of what's been going on. I suppose only those of us who have been through it get that, hence posting here for a bit of support from those who do understand.
