HELP I don't know how to make new friends in my form and I'm usually all on my own 😥

so there's this guy and we had/have a thing but I told some people some stuff like about our conversations that he didn't want people to know about. he forgave me and everything seemed good. I promised him I wouldn't tell anyone anything without his permission. I broke that promise. he doesn't know. should i tell him even though our relationship is completely screwed? we barely talk anymore. we used to talk everyday.

HELP!!!!

so my friend and her other friend do everything together. but I like her other friend, we are all like a group of 3. but you know the saying. threes a crowd. well, they are going everywhere together semding me pictures, and I feel ignored. helppp
