What is his intention?

There is a dude at school i met him like a month ago he asked for my number and we started to talk at school he is very flirty and he kept complimenting me, hugging me and telling me how much he want me he also ask me for date which i refuse because i felt like he was moving too fast

Then we started texting the thing was he lies and act like he is in love with me meanwhile his profile was a girl and his username was her name when i ask him who she is he told me to not worry about her because she is no one

I started to fall inlove with him and we talked a lot he even asks me to be together i was going to say yes but then he accidentally called me by the name of the girl in his profile

I stop talking to him after then i thought he would come back and apologies but he ghost me and what's worse is the next day his profile pic was their picture together her kissing his hand

So tell me what should i do if i see him at school and he tries to talk to me

What is his intention?
