When one side of a relationship threatens leaving because of the other side, its the most manipulative and wrong thing they should do. Let’s think about this…your bf/gf says something like “you’ll miss me when I’m gone,” that’s so rude. They don’t realize not only are you losing THEM but they’re losing YOU as well. Do they think they’re more important? I don’t understand. If you are willing to walk away, assuming I’ll be devastated, then you aren’t worth my keeping around. I’m not shedding tears over someone who is willing to walk away and sacrifice a relationship to hurt me. We should be losing an EQUAL amount and the thought of you walking away should hurt just as much for you. So hey, you’ll miss me when you’re gone too.
