We had been together for a month and a half. Three days ago, we had a small argument. While I was trying to talk things through and resolve the issue, he didn't want to talk, which caused the situation to drag on much longer than it should have, and we didn't speak for three days. We finally talked last night and decided to meet up. When we met, he postponed the discussion again because his friends were there. I don’t know what came over me, but even though it was my first time meeting his friends, I caused trouble and acted moody all evening. Naturally, his friends were uncomfortable. Eventually, he said he’d take me home, and we left.
On the way, we talked things out. We resolved our issue and apologized to each other. He even kissed me for the first time. However, after we went our separate ways, he broke up with me via text. My English isn't good enough to go into every detail, but considering how I acted in front of his friends, I completely understand his decision. You can imagine how uncomfortable it is to have someone you’ve just met sitting across from you, acting moody and irritable. I embarrassed him in front of his friends, and I truly regret it. I apologized to him and offered to send an apology message to his friends as well, but he said it wasn't necessary.
I’m not just saying this to change his mind; I am genuinely regretful for my behavior. That’s a separate issue. I’m wondering if there is still any hope to fix things. I really liked him, and we were very compatible until this point. He ended things very firmly in his message without being hurtful. The fact that he was so considerate even while breaking up makes me feel even worse because I failed to show even a fraction of same sensitivity.
I had given the bracelet I bought him as a New Year's gift to the jeweler to have the size adjusted. I also have his helmet. He's going to come see me in a few days to get them back. Is there anything I can say or do?
TL;DR: I acted out and was moody when meeting my boyfriend's friends for the first time due to a build-up of tension from a previous argument. Even though we made up and shared our first kiss that night, he broke up with me via text shortly after, likely due to my behavior in front of his friends. I’m deeply regretful and he's coming over in a few days to pick up his things. Is there any hope for a second chance, or any advice on what to say when I see him?
