Dating a Muslim Boy?

Holly • Be the best version of yourself :)
Lovely ladies, I've been seeing this guy for a year and officially dating him for 7 months now. My thing is, he hasn't told his sister that he lives with, his other sisters or his parents. We don't have out status on Facebook but he tells me he loves me and he's really genuinely sweet. He tells me I have to wait until he knows for sure, but then we have amazing sex and do all the things couples do. Is this normal for Muslims? Or am I believing in nonsense?
