So a few a days ago my ex boyfriend started texting me every night and still does but he doesn't text me during the day and I'm just really confused because he was the one who broke up with me. He told me that after we broke up it was really difficult on him and he couldn't stop thinking about me. He also asked me if I was okay with him wearing a necklace I had bought him. I'm really confused. Is he just playing with me?
