so today at work I almost got into a fight with a co-worker. A co-worker that's a old school friend. Everybody was joking around at work and then his girlfriend who also works here said a joke about me giving him advice about his sex game under her breath, which is funny cause im a virgin. He didnt hear it fully and asked me to tell him with a smile on his face and so after the 2nd time asking I did.I guess that kind of pissed him off. I couldnt tell it and didn't think it was that big of a deal, Clearly by the way they talked before she seemed to like it(their sex life). Hours later, he starts to act kinda quiet but I figure hes just giving her the silent treatment or something so when she ask me to talk to him I laugh. More hours, They kind of get into an argument, he tells us to wait but we got to take a order out, she gets annoyed with waiting and starts to walk outside and he runs over and he gets kind of aggressive. She throws a fit and he starts talking about how she doing it again even though hes been at it for hours so i point out that he's being kind of sensitive. He loses it kinda. I asked him if he's serious and is he really upset about the situation and he threatens to fight me and to stay out of his relationship and I tell him I dont care about that I wanna get work done get closing over with and we dont need none of this, he said another threat, I told him Ill beat the spit out of him as He walks to the backroom yelling in there and I start walking his way till his ready to beat him a new one, girlfriend just ask me to cool off outside. I already hate my job but now it's just becoming more and more I have to deal with so I gave my two weeks notice. When I went to work I just kinda ignored him and he broke the silence with work talk but i dont completely talk the same, partly cause Im just mad he'd fight me over something that silly and cause the back of my head kinda wants a fight now that he had the gull to threaten me. Im nice enough to still help at work as it seems he is as well. I don't like losing friends but I will if I have to. Was it out of my place to say anything? Should I have just fought him? We were really good friends. Had this been reverse I definitley wouldnt have gotten pissed. I think its silly. Even if I had issues with my girl, Id just dump her if she was being a ACTUAL bad person. Am I a bad friend or honest? ( Extra info, He and her both asked of my approve of their relationship for some reason when I learned of it by accidental snapchat post, He ask my opinion of it once or twice after they both did, HE ALWAYS BRAGS ABOUT HIS SEX LIFE, He and her both know Im a virgin in a relationship, and he always gives me jokes about being a virgin pretty funny ones at that ive never gotten upset about, He also bring up the day I got into a fight and how he was ready to beat up the guy I already beat up for me (3 of my other friends did this as well) which i told them is settled because I gave him hands. With his ex, who I knew from economics, he asked me if" I knew his girl?" and I said yeah dude... We had economics together she sat right next to me, he asked me the same question 2 more times.
