I suppose an ex did, in a way.
Was whilst I was at uni. We were friends for a year before anything happened between us, so by that point our two groups of friends had amalgamated. When we split, then, I thought it best not to really tell people what had gone on as they were all good friends with him too, and I didn't think it was their business.
Things between me and most of the group cooled to some extent over the next wee while, but I wasn't too bothered. I just assumed it was the way things were, especially when the ones a few years older left uni and moved away.
It was not until a few years later, when ex's next relationship had broken up, and one of my old friends decided to fill me in on the details. The lass had dumped him because she felt suffocated, and this had come to a bit of a surprise to the group as a whole. So friend was rather taken aback when I said we'd split for the same reason, and said that ex had told them it was all my fault because I was so difficult, which is why they'd pulled away from me.
What hurt was the fact that they'd all chosen to believe this without running it past me. I wasn't going to volunteer information, but would have given my side if asked. I wasn't so bothered by those who had been his friends first, but it was my friends who I thought knew me better who upset me.
