What does he want?

My best friends brother has started hanging out with us lately and we’ve come to be very close as in cuddling, hugging and such. The thing is he gives off all these vibes that he likes me but then he does something to confuse me.

Like we slept over at their place and he was fake kissing me the whole time but then he really kissed me and for the rest of the night we would secretly kiss every chance we got, then the next day he was really distant just not the same can anyone tell me what he could possibly want.

I’m very confused because I’m really starting to like him but I don’t want to get my hopes up if he’s not in it.

Can anyone help!!
