I have a crush on this guy but he keeps sending me mixd signals!!?

There's this guy ive been talkin to on fb [ive met him before] well when we were first talkin we were cool &!i started likin him. We both always sent each other i love u's & hearts.I finally told him i had feelings for him & he said he did too! Everythin was good & ii asked him if we were single n he said naa never,soo the nxt day i sent him a relationship request nd he strted acting diff so i askd him if he likd me as a friend n he said yea! & when i told jim i liked him he sounded happy n calld me babe n stuff. We stopped talkin on n off . But all of a sudden he started likin my pics,status n **** n messaged me last nite saying 'myyy cheeesecakee' (he calls me tht) in our convo he kept sendin winky faces. Im so confused! I still like him i realized that.:( waht do i doo??
