I think I destroyed my friend’s relationship

So, this is a long post, and I’m sorry I have to remain anonymous. I had to delete my post history to make sure no one figures out who I am.<br><br>I’ve been friends with this girl for quite a few years, but she recently started dating this guy who’s kind of an ass. He’s not mean to her face, but he’s said some really racist shit to me.<br><br>I confronted him about it, and we got into a massive argument. He told me to stay out of it and to never talk to him again.<br><br>Well, I was out with my friends last night when I saw him. I completely ignored him, but he kept pulling me away from the group to tell me off. He called me a bitch and told me that I was a rat and a little girl. I told him to fuck off multiple times, but he wouldn’t leave me alone. So, I stood my ground and slapped him.<br><br>Now, his girlfriend is pissed at me. She says that my actions were immature, and that I ruined everything between them. I don’t understand how it’s my fault that he can’t let shit go and that he disrespects my race. I don’t feel bad. I feel like I did what I had to do.<br><br>Edit: He called me a spic and a wetback plus other things and that must have triggered me because I was called that and other things as a kid. Don't know if it helps but that is what happened. I’m sorry if you feel like I did something bad or if you feel like I ruined everything. I didn’t have bad intentions, and I just want to fix everything between us.
