what does this mean?

so this guy that i met at work, we’ve kind of formed a friendship and we instantly hit it off, and we’ve been texting and snap chatting on and off. Well, recently he texted me telling me he was down to do things with me if i wanted to, and i do but i thought he was messing with me. well just last night we were talking again and we traded pictures and i told him not to show anyone and he said “i won’t. i don’t want anybody else seeing my girl.” im flattered but also confused. does he like me? is he just entertaining me?
