At one point during your romantic history, you've undoubtedly encountered a partner that, when you try to end the relationship, refuses to accept it. As frustrating as that can be, it's important to consider your former partners behavior and why they aren't able to let go.
Getting over someone after we dated for awhile used to be such an ordeal for me. I'd stay hold up in my small studio apartment playing these sad ass love songs, listening to their voice on my answering machine over and over, then either looking at a picture or some cheap trinket that they brought me. I was pathetic. Thank goodness I moved on from that.
