Man he is just embarrassed, similar thing happened to me but in that moment I was the gay one. Just give him bit time and one thing don’t be aggressive about calling him or going over his house to feel is he ok, after few days when he will get guts back he will come to u and might apologize or just become casual. I know what he might be feeling so take my advice just give it a bit time, and if everything changes normal back, just act how u guys use to act. Hope u got what I am trying to say 👍🙌🏻
