I ruined everything with my ex, now I don’t know what to do

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.

It is what it is. When things head south it's natural to want to reclaim a bit of the investment, symbolically. Sure, you unleashed some anger.
I would say go enjoy yourself and try to pretend he isn't there.

Hi socksbaby.

Sometimes we say things we don't mean in the heat of the moment....when we allow our emotions to get in the way. However, in my opinion there is no good reason for you to be contacting this ex boyfriend. I understand that you feel dejected and angry toward him, but the necklace was a 'gift' in happier times.....what he does with it is up to him. I'm thinking that you asking for its return may be an attempt to control and cause hurt....which is normal after a breakup. But my advice is to simply move forward, create new happy memories with someone new....breaking up is part of life.

Yes, sometimes we say and do hurtful things through a breakup. But your insistence on receiving back a gift you had given him was wrong to do, I have to be honest with you. You should never ask for a gift back. It's a gift, and even through a breakup, we don't ask for them back. Hopefully you can forgive yourself for your hurtful words, and hopefully you will have a chance to apologize, but I would not contact him again. Unfortunately, that bridge is burned and his ship has sailed away. I hope for your own sake you don't run into him at the concert.

This is just my suggestion.
Send a text. Explain you do not expect a response and not sure if he will even see the text since may have blocked you. Apologize for asking for the necklace back. Apologize for getting so upset and saying things out of anger and you didn't mean. And everything else you need to say. End it with you understand if he doesn't want to respond and you will respect his wishes to have no more contact.
You're doing this for two reasons.
1) if he sees it, you'll be able to really apologize for acting so immature.
2) for yourself. You are saying you peace. Then let it go.

I have ton and I literally mean ton of expensive jewelry from my ex. These were gifts. For birthdays and other holidays. We were together for a long time. I left him because relationship stopped working out for me. I can’t imagine him asking me to return things even though he was very miserable that I left. I got him nice gifts over the years too. Most certainly would never ask for them back.

At this point just leave him alone. Try to move on maybe with help of a therapist but don’t contact him again.

Totally random question though. You were very young when you were seeing this guy. You are 18 now and you weren’t even of legal age then. How could you afford lui vitton?

I would not make further contact with the boy. Also that necklace was a gift so he does not have to give it back.
