For me it was more acquaintances, a group myself and my ex were part of. I took a step back from meeting the group as a whole because I wanted to avoid my ex but kept in touch with a few I was friendlier with. Ex continues to meet the group, and that's fine, I don't expect people to take sides. He discarded me very coldly in the end and was quite nasty to me in what he said, and that's why I continue to avoid him, but never told anyone in the group exactly what was said and what happened. I've recently seen photos of them all in a group setting and I felt a bit low after it. I have to say though I've good friends of my own though and spend time with them.
Anyone else experience similar?
