I need friends who cares for me

I do have friends irl but just 2. And after i brokeup i realised that i don't feel close with them anymore. They r still friends with the person i dated even after knowing that he cheated on me and asked me ***. And few weeks ago one of them called me saying he texted her and showed me their texts, they were having quite fun conversation. I was soo sad when she showed me their conversation. And when i didn't knew that he was cheating on me, one of my friend said that he started dating someone else even when i wasn't moved on from him. I don't think that they even care about me anymore. They just do what they like without caring about how their actions might affect me. And from then i can't trust anyone nor can i share my fweing with anyone.
