So my ex boyfriend broke up with me and went back to his ex supposedly because I cussed at his aunt, but I've apologized to him several times and told him that I feel bad and I've cried to him about it and he's told me "It's ok. It's in the past." And I saw his aunt once shortly after the breakup at his birthday party and I apologized to her and he said "See? Why don't you be friends again?" I've apologized to him several times after that and that's when he's told me "It's ok. It's in the past." But he still keeps bringing it up! Why?
