sometimes I just can't get over things like when me and my boyfriend frist started dating we were on a date and this random person came up to us hugged him to find out she was an ex and he didn't tell me until months later and she cheated on him when they dated and then one time we were in the dollar store she seen us and tryed talking to him and I told him you better tell her to never talk to you again which he did but I just can't get over it cause it hurt my feelings at one point.....
