When we were dating, I had given my ex a Louis Vuitton necklace. After we broke up, I knew he would just throw it away, so I asked for it back and he said he would mail it. A week later, it hadn’t come in the mail, so I texted him and asked if he mailed it. 2 hours later he posted on Instagram so I know he was on his phone but he still didn’t reply. 24 hours passed and I texted him again. He didn’t reply to this message either. I know he is on his phone a lot and I knew he was deliberately ignoring me. Out of desperation, I texted my friend and asked what I should do because he was making it impossible to get in contact with. My friend had the idea to put him on a 3 way call. I didn’t talk at all but she was very polite when he picked up and said that she was my friend and that he had something of mine and that I wanted it back. He was very rude and blew her off, was basically like “yeah yeah whatever” and then hung up. Then I started getting angry. I called him and he didn’t pick up. What happened next I realize I ****ed up. I rarely get very angry, but something about the situation triggered me to get very mad. I cursed him out over text message. I realize I went too far. I’m not gonna say exactly what I wrote but I called him a bum and told him to grow a pair. Then he responded saying that I was crazy and a maniac and never to talk to him again. I realize that cursing him out was very low I wasn’t thinking when I was doing it I was so angry. When I calmed down, I realized how hurtful my words were and I tried apologizing to him but he didn’t accept my apology. I still feel horrible about what I said and I feel like I should apologize to him again but part of me feels like I should just leave him alone. I truly feel so sorry for my hurtful words and for letting my anger get the best of me. I’m going to a concert next month that I know he will be at. I hope he doesn’t see me because I know he hates me but it’s a small venue so its likely he will see me. I don’t plan on talking to him but I was thinking that maybe I should apologize to him before the concert because I feel really bad and also so things aren’t so horrible between us if I do run into him. Or should I just leave him alone and hope we don’t run into each other? I really don’t know what to do, help.
