I just met this dude and i was waiting for the bus and he came and holla at me and yeah so we were talking for a minute and i gave him my number and he gave me his and yes i called him and i probably talked to him like about 2wice and he told me to call him back and he didnt pick up then i call back and i dont know if it was him or he was facking talking about that that wasnt his phone anymore so dont call that # anymore and i asked who it was and he said his father.And i got so pist off i really wanted 2 talk to him i really tought he was the one i really liked him to.He even said he liked me so much ever since he saw me. But wat should i do keep calling or back off i mean i dont know if it was him or his dad?And faking on me???????(he was the one who came up to me to get my #).
