So out of no where literally the beginning of this week my boyfriend has been acting weird and we were trying to solve it yesterday and then out of no where he said he wasn’t happy and idk what I did to make him unhappy. I’m not sure where he stands I feel he might end it but he told me the only reason why would be if I cheated or he lost feelings would be the only reason why he would end it. I said why aren’t you hurting like me and he was like in thinking what is best... he is the love of my life idk what else to do please
