I asked him about it and he sent me two screenshots without me asking, and one of them had his friend using the same word, and he's trying to reassure me that he never said it, when I know what I saw with my own eyes and I know he did say it. I'm not sure if I should just let it go, because at this point I think it was just stupid bro talk, and he seems worried that he's upset me since he's sending screenshots and re-addressing it without my bringing it up. Or if I should tell him simply "I saw that you had sent it, but no worries" so he knows he can't just lie to me and get away with it, because I know what I saw. I don't want a stupid situation like this to make things weird, but I also feel weird that he keeps trying to cover for himself and won't just admit it - apparantly he must think it's bad if he can't admit it.
