As the title states how do i know if an ex is in a rebound relationship? She broke up with me after 18 monthes and told me she didnt want a relationship and that she wouldnt be in one in the foreeable future. She said she didnt have the time or energy to put into a full blwn relationship. Now after a few rough rough monthes dealing with her she is in a new relationship with someone she used to make fun of and say how he wasnt attractive and always high and such. does this sound like a rebound relationship?
