I need adviceeeee

i already talked about this on my other entry but whatever!!! I need advice on something!!! (tw: lots of typos since im mad)

I recently started dating this guy online! hes amazing and hes legit my everything!!! but thats not the problem.... (for the story I'll refer to him as S)

S had a friend who is quite........ jealous to say the least!... (we'll call him C)

me and S got together 2 weeks ago after knowing each other for a few days, which I know is soon but we really had a bond and clearly romantic feelings for each other! C didnt like that at all.. C didnt like me for the beginning! its very obvious that C likes S!!!! I knew that and got together with S anyways since thats not my problem! 

but now C keeps posting abt us and its so patheticccccccc!!!! but I do feel bad for him yk??? I would apologize to him IF IT WASNT FOR HIM SHIT TALKING ME??? he also tried to make me look bad infront of S but it clearly didnt work :p 

I also know that S feel uncomfy abt them and also thinks theyr pathetic.

So now I need advice: Do I call out C on their tweets and actions? or do I ignore them??? whatz yalls opinion??
