Chinese friends

Hi everyone I just wanted to share my experience, and to spread awareness too. I was just scrolling through my black app when this one video caught my attention and it says like this "finding international friends" then because I am bored at that time I commented finding friends. Then this one chinese guy who replyed and we became friends, at first I thought he was just a random poser and catfish but when he started showing pics I believed him. Because I tried to search those pictures that he send me on google and pinterest, to make this long story short he started being clingy and I've fall for him, but I was kinda skeptical about her "Childhood bestfriend" she's a girl and they were so very close I noticed that they weren't really friends because this girl come to his apartment and they slept together in one bed, I brushed it of in my mind cause every childhood besties were really that close. Until this happen, we became friends- the 3 of us we became close and we always chat. Then after 4 days this chinese boy said "I need to tell you something" then it wasn't him, he gave his account to his girl cousin to tell me everything- that he and that childhood bestfriends were really girlfriend and boyfriend, and I am not mad about it because I understand, I am mad because I can't accept that our friendship has to end like that, although I fell for him, and he fell for me aswell I can't really understand how her girlfriend never found out about me and this boy when they only use one tiktok account to talk to me. I hope they find this because they already deactivate their tiktok and I don't know about theyre socials, keep awarness everyone that don't talk to strangers that easily, don't ever try I don't want everyone to get hurt... and those chinese were somewhere out there I hope that you both guys happy now wish you all the best.
