Relationships

Okay so my fwb kind of fucked me over he randomly stopped talking to me and then I found out 2 weeks after he just got a girlfriend and never told me and I confronted him and he apologised for not telling me and admitted he fucked up and now I'm obviously very upset but I really don't want him to know that I want him to think I'm okay and it didn't affect me at all because he's the type of person that would be abit jealous of that and basically the whole reason I'm writing this is because he is getting his final exam results on Wednesday and I was thinking of sending him a text tomorrow saying "hope everything goes okay for you tomorrow you freak:)" and I obvs won't reply to his reply, it's just to show idgaf and all good vibes also
