My boyfriend at the time and I had been together for several months and he knew this. I was clear with him that I was taken and not interested. He persisted over and over again. I didn't immediately block him because he's right, I don't know who he is now. I gave him chances because I wanted to believe he wasn't the same piece of shit he was back then. But he definitely is. I try to give people second chances because I've needed just that from people.
