Ghosted on me

So i was talking to this guy and he just stopped talking to me. he kept leaving me on read, didn’t respond to me, didn’t come up to me during school and i found out that a girl named Ari started talking to him. she just broke up with her bf so i’m assuming shes getting with my man. she also has a girl crush and i’m bi. i’ve been talking to her girl crush trying to make her jealous. her girl crush likes me back and i’m not sure what i should do. plz help me with ideas. p.s. i also have a crush on the girl crush. sorry if this is confusing.
