I have only been the one broken up with, I have never ended a relationship. So I was curious what being the dumper is like? I had one girl who would come back in 1-2 days and want to be back with me even when I was a crappy BF. This last girl I was great and she broke up with me for some personal reasons that I could not control and it’s been 40 days and I’m totally blocked out. This leaves me highly confused on how this works? Like what do yall think when you break up with somebody and do you regret it? Does it start creeping up on you later? If your partner was genuinely a good person, do dumpers tend to reach back out months later?
