Is it normal for a guy to ask a girl out, right after her grandmother's funeral?

TO THE LAZY READERS: You can just answer the basic question above, if you'd rather do that. lol.

OK, I had been texting this guy I knew when I was in high school. We weren't super close. My grandmother died and I didn't invite him (no need to, I think it's kind of wrong to make someone *whom you hardly know* feel obligated to come to a funeral) to the funeral. Well when I told him she died, he said he was sorry and that he knew what I was going through. That's fine, OK. But then hours after I got back from the funeral, he texted me, basically saying "I like you and I think you're a beautiful girl too. Wondering if you wanna go on a date with me?" Well, IDK why, but I said sure, I'd love to "hang out" with you, but I never implied "date". I didn't know how much I liked him. But then he got all excited about the "date" and I told him "I think I'm giving you the wrong idea. I don't want to lead you on. We could hang out as friends, but not really date right now". Then he said "oh OK" and I said "sorry" and he replied with, quote-unquote, "it's like whatever now", like he didn't really care much for going out with me to begin with.

I'm not a guy, so I'm a bit confused. We're not going out and we're not really friends anymore, either, because it's super awkward. He just stopped texting me. I don't really care because I hate being social. But I'm just curious, is that normal for a person to ask out someone after a close family member's funeral? Do you think maybe it's because the person is already vulnerable and likely to say "yes"? Sorry if the question's a bit long. I'm just looking for opinions. I didn't want to think I was a total ***** for leading him on, but the fact that the date invitation happened when I was already grieving got me confused. If it were me, I would wait at least a week before I asked a grieving friend out on a date... Opinions, please? Maybe I'm just looking too far into it, but I'm honestly curious.

Thanks!
