If a guy is very concerned and always makes sure you're safe....what does it mean?

So this guy is very flirty with me, but also, he is very considerate of me. He always makes sure I am okay, and if I'm sad he always knows and tries to cheer me up because he says he doesn't like seeing me sad. Also, he always messages me and says "I hope all is well" to me and if I tell him I'm out with my friends he always says "Be safe".?

Also, he keeps on mentioning he will come and see me and work.

Also, he keeps on suggesting we do stuff together...?
