My best friend is alsio my ex and was my first sexual partner and relationship all in one , me her do coffee most days. I also see a couple of ex bfs /fbw around too. Never had bad break ups either it wasn't wotking and we both knew it so knew the end was comming so easy to stay friendly with them
I'm friends with and occasionally see one ex and his wife. It's a little unavoidable because I'm so close to his family that our paths just cross. We workout at the same gym too. His wife is nice and so I'm just happy for him.
