Relationships 🙄😭😭

Okay so I have this person I like. his name is Dominick and hes mixed. Ik bestfriends with his sister. Me and him started to talked for a while. Then when I went to her house he told me that he liked me and I said me too, well..... a couple days later I found he just started dating someone (the biggest hoe In school) . But when I asked him how he felt about her at my varsity game ( I cheer) he said she was following him and he called her a hoe. And then the next morning I get a text saying I need a ride to school could you take me .... and I was like wait , why you asking me for a ride ask your gf for a ride. And he said are you really that mad about it . Like really come on , you don't just lead a girl on like that and then now you're going around posting about yalls relationship and how you love her so much. They already broke up once and then he crawled back to me if it happens again I'm not fallin for it 🙄 I don't understand how you lead someone on after being all up and close and then you just drop them .... it hurt me so much 😔😔
